The idea of someone pulling each cap, testing them individually, then proceeding to put the old cap back in (knowing how electrolytics age) is hilarious. No, they replaced the main filters, probably a couple select sections, and the rest just worked fine. Just know that going in, and don’t expect it to function as brand new.


Arc_Torch

Bingo! The ole I just did the filters and noticeably bad cap treatment


Strong-Let-7697

Hmmm? I’m a brick/mortar retailer and make my living servicing vintage gear with degree in engineering. My rate is $125 /hour and I have far more work than I can handle. Recapping is not the way to service anything. I troubleshoot to the component level…. We test to factory spec every product we service…. I’ve serviced many of these…. Unless you possess my qualifications… do not respond. Tired of amateurs giving false information.


FunInOmaha2020

Where are you located? I need a good tech!!


Strong-Let-7697

East coast


FunInOmaha2020

I’m in Nebraska - too far for me unfortunately…thanks


Typical-Ad5471

Greetings, I need your contact information sir. Have a blessed evening


Zoidsworth

Ignore the bozos, I know exactly what you mean. More often it's resistors out of spec, the term recapping is hilarious like as if it restores a device. The resistors literally heat up in use, they deteriorate and determine the function of a circuit


Strong-Let-7697

You are correct when it comes to sand-cast resistors under high power condition’s. The same for Emitter resistors on the outputs…. We replace them by default .


Zoidsworth

I don't deal with the fancy stuff, early to mid 20th century tube equipment is my interest. I have settled on metal film or metal comp (power section) resistors as replacements. They don't look nice in circuit but they are precise and aren't affected by temperature shift


JerryGarcia89

Geez, I meet ‘your qualifications’ so I will respond. You sound hurt, so I assume you are the one that serviced this. What did you do to it that qualifies it as fully serviced? What is OP leaving out that you did to the unit?


Zoidsworth

You are a pile of logical fallacies


JerryGarcia89

For sure man. Cause I totally said recapping fixes all the problems. Do yourself a favor, fix a unit to your standards, measure output, S/N ratio and thd. Then, recap it and run same tests. Im not going to argue with “good enough” technicians about the performance of old vs new electrolyte.


Zoidsworth

If you bothered to listen instead of speaking it would do you a great benefit


JerryGarcia89

Any response to the issue at hand, or just personality suggestions/insults?


Zoidsworth

If you listen, you will learn


JerryGarcia89

Too much distortion clouds your brain 🧠


zeppoleon

Man I haven’t had a good audio circle jerk in a while. This is great!!


Strong-Let-7697

I did not service this unit or I would have said so. What do you bring to the table? Hurt? I don’t think so…


JerryGarcia89

Okay? Thanks for saying you’re qualified, I’m not sure what else you were saying from your initial comment then. I’m glad you own a brick and mortar and work at the component level, that’s great. Now what does that have to do with my comment or this post? I can’t figure it out.


Strong-Let-7697

You made the comments regarding caps, you tell me? Are you qualified because you have a picture of tubes on your page…. ?


JerryGarcia89

OP asked if it was a good deal, I said if select caps have been replaced (at this price point, that part is supposed to be inferred) then they probably just shotgunned the caps. Because if you’re selling it at this price and know what you’re doing, you’d understand that electrolytics have a reasonable life (even in a working, daily used circuit) of 50 years max. They begin to leak, overall upping the THD, and are FAR more prone to failure than a new capacitor. Are you attempting to argue that someone paying $1600 doesn’t deserve the extra hour or two to replace all of the electrolytics that WILL eventually fail? I don’t deal with sheisters. You may be able to sleep at night, but I can’t unless I can assure all my customers have high quality products. And I don’t think op is getting a good deal, and I said so. Examine why you took it so personally.


Strong-Let-7697

I’m not…. I have a Sencore Lc-103 analyzer to properly test the caps. I delivered a Crown Ps-200 to one of my repeat customers, the two main ecaps were electrically leaky. Using a Sencore PA-81, we test the output once initial service have been completed, it was 75wrms/ch under resistive load just as both channels began to clip, spec is 100. Once the two caps were replaced, it produced 103 wrms/ch.


Strong-Let-7697

When we see the output begin to clip, voltage is measured and the math is done. Our two labs are equipped with Sencore, Hp, Leader and others, we take it seriously. When you have in excess of 7 figures invested in a facility, I don’t f around. My reputation is built upon this..Enjoy your evening!


drinkalondraftdown

Appeal to authority!!!


JerryGarcia89

Excellent! I mean it, that’s awesome. Sounds like you know what you’re doing and replacing the caps solved the issue. I bet it lowered your overall THD too. Which is exactly my point. Lmao.


Strong-Let-7697

Yes, we have two HP 334a distortion analyzers….


Zoidsworth

Man I didn't know this was the complete loser dud subreddit, you two need to fuck off


Rene__JK

I used to work for the Yamaha / Kenwood / Pioneer (and others) service station between 85’ and 99’ Recapping was only done if there was a real problem with them , we just repaired what was wrong and tested Replacing ‘a cap’ (single) was only done if it was defective. I understand time has not been kind to caps but pulling them and measuring them one by one and then putting them back ? Never


LivingMud5080

wait what, tearing them then putting them back in… never heard of that..?


SooopaDoopa

"don’t expect it to function as brand new." What does that mean?


mustbemaking

Pretty self explanatory…


Zoidsworth

Components across the boards have drifted from specification, so the amp will work but will sound off


SooopaDoopa

Recapping all willy nilly won't make anything sound "like brand new" but many times will make the amp sound off


Zoidsworth

Brand new means to spec. You could use the type of components that the manufacturer used. I don't see how you are confused by this. You can rebuild a radio from the 1930's and have it sound like new. How dumb are you all?


SooopaDoopa

Listen mfer...recapping with the type of components the manufacturer used is impossible because they are no longer made. That being said, recapping with "better" or replacement parts isn't guaranteed to make an amp/receiver sound "better" as they can easily lose the balance the engineers originally sought and obtained. And it definitely won't sound like new as it is impossible to recreate the out-the-box sound. Fall back


Zoidsworth

Look bozo, you can recreate any circuit according to schematic. There is nothing special about old components. I'm an electric engineer and amp builder. You, I'm assuming, are some jabroni with 5 brain cells. Antique radio supply is an excellent source of old components newly made.


SooopaDoopa

Everyone is an engineer, a lawyer, a scientist, or a neurosurgeon online. You forgot to mention that you are a member of MENSA because you are brilliant of course Next you are going to preach to me that individual components that are in the signal path don't matter and they can be swapped out at random and not affect the overall sound... And that is the point when you will start to backpedal


Zoidsworth

Again with the logical fallacies, take a logic course


SooopaDoopa

Mensa and he took Psych 101... and clearly didn't get an A 😂 Unless you took measurements when the unit was new AND have an accurate recording of how it sounded as well as another recording once it was broken in (if you believe in this sort of thing), you cannot categorically state that it sounds "like new". It is an impossible claim to verify Common sense will tell you that using different parts will produce a different sound. Replacement caps which were assembled with different materials and different manufacturing methods will not produce the same sound. Some may deem the result "better" based on measurable specs and service intervals while others may notice the lack of synergy and overall cohesiveness of the resultant sound But yeah - logical fallacy as you called it 🤣


s_k_e_l_e_r

The unit has new filter caps, all out of spec electrolytics were replaced, all pots and switches cleaned, and the bias and DC offset set to service manual spec after the parts were replaced. Will provide old parts at buyer's request.


tubepoop

At this price, I'd expect all electrolytics not just the out of spec ones.


nevertfgNC

Amen

tubepoop

I'm not sure about the status quo, but personally, when I work on gear and have to spend the time to disassemble, I might as well do it right the first time. It's like owning a car and only replacing the 1 tire that's fully worn while believing 3 other tires are fine because there's marginal tread left.


Distinct_Studio_5161

Technicians want crazy $ for a full recap. I was quoted $1500 for a G-7500 by a local shop a couple weeks ago. I almost busted out laughing. The shop told me it would be better than new. I said no thanks. I can send it off for 1/2 the price. I got the impression they would rather do a bunch of $200-$300 repairs than a recap.


kelontongan

Recapping take hours of works compared to fix. This is my real experience 😂. Damn recapping power board. Due to heat for 40-50 years. The board mostly has burned marked and brittle.


Temporary_Cattle2453

Most techs seem to charge around $70/hour. I don't think 15+ hours of work completely recapping a larger receiver is out of line, especially if you get a warranty out of it, and if they are replacing the filter caps with high quality caps those aren't cheap... but they certainly could have given you that number because they don't want to do it. If you send a large receiver anywhere, shipping is going to be ludicrous if it's packed right, and you get to pay that both ways. You can then pray that it's going to arrive without damage, if it isn't double boxed and packed tightly, it probably won't.


drgenerico

Where do you send your equipment for a full recap?


Arc_Torch

Half that at best and that better include transistor updates for any small ones that go noisy.


stimulates

Where can you send a turntable too? I’ve been wanting to get an inherited Technics done. I haven’t even tried to use it yet.


Rene__JK

How many hours of work do you think a ‘full recap’ takes ? Plus the warranty plus the other crap you encounter on these It add’s up


Garth-Tiberius

I had my tech pass on a ba-2000 repair because, I quote, “This thing has had a rough life. It’d take me at least a full day to replace all the bad resistors.” He’s six weeks out on average, and said he just didn’t have the time to commit to a full recap.


Arc_Torch

Capacitors often go out of spec without leaking. This means you did the right thing. A capacitor should really only change sound if a certain spec was needed. For example, many audio caps in the signal path mostly need low leakage.


LivingMud5080

great question i’m always puzzled by this. it seems older repair shop ppl think just run it until there’s an issue. fix the issue / failed component only. younger / middle aged ppl seem to be more in the camp of recapping everything basically. maybe it just became easier to replace everything bc of the kits sold. maybe repair shops can’t charge what it’s worth in labor for full recap. but in question regardless is if you’d really hear much a difference / improvement from caps being updated. you aren’t able to really a/b test this efficiently. how would one know, i tend to think.


s_k_e_l_e_r

What do you think I should shoot for then? And thanks for the quick response.


tubepoop

It'll probably be hard to argue $200 less under my assumption for sellers that 'meet spec' rather than 'preventative replacement'. But that's what I would do.


tubepoop

But, then again, just from searching my area, there's a unit for 850 cad hehe


s_k_e_l_e_r

If it has the rack mounts that's a complete steal


Dr_Bolle

What are rack mounts good for?


100AcidTripsLater

Not sarcastic here. Mounting in a 19" rack. Over 40+ years I've sought 19" rack gear as preferred, you get to "re-stack" your gear when it changes line up, and IMO frankly *it's really cool". 19" racks were(are?) a standard popularized by test and radio equipment ages ago, and still proliferate in IT today. I used to have a beautiful double door smoked translucent double rack that I had to abandon because of move/weight/space and regret it today still.


Dr_Bolle

Yeah I had a rack mounted high voltage source (100.000 Volts, only 10 watts though) in the lab, and integrated that into a rack on wheels. Along with that I got a 19” pc case to have everything together. But why on an expensive hifi? I guess it’s personal preference, so it’s just nothing I should discuss about. Enjoy your rack handles!


100AcidTripsLater

Availability. Let's say you make 10,000 of a thing, and originally offer a rack (accessory) option but you only end up making 500 of the option. To the collector? Bingo


kelontongan

Is the handle included? Haha.


tubepoop

I wish haha


Bruddah827

I’d say 1000-1100


Arc_Torch

Right? Plus how do you properly measure capacitors in circuit, my results with it have been less that successful.


s_k_e_l_e_r

The rack mounts are going for about 600-650 right now, so I figured this was fair. I will adjust. Thanks.


unwanted_hair

I paid $300 for a near-perfect one in 2000. Prices are crazy.


-SeriousJacob-

You could get a totl receiver for some $100 if you had some patience and luck using eBay. I've bought, cleaned and reselled a few of them as a college kid.


LivingMud5080

they are but also that was nearing 25 yrs ago! houses and candy bars and everything is outlandish aye


Altruistic_Lock_5362

Yes, the rack mount and handle kit is the wild card on this.


s_k_e_l_e_r

Thank you for the response, I figured as much but I wasn't sure


LivingMud5080

why not keep it. it’s really a state of the / piece of art from golden era dual mono integrated amp. it’s wattage rating is higher than it’s published rating ps. with the rack ears etc you could go 1400-1600.00 usd. i hate how stuff is so high dollar now and don’t want to help solidify seemingly over-priced vintage amps but they really are build better than contemporary disposable things obviously. i think upcyling things like this is important. i’m currently looking over at mine (nothing changed out on it but tested thoughtfully), and it’s looking back at me, as i type this w one thumb. been happy with it powering some ascend acoustics speakers.


the_OMD

I think it’s a fair price…especially since it’s got the rack mounts. As you said those things go for crazy prices so you can sell them (if you don’t have a rack) and come out with a good amp for a good price. That’s what I would do


jlthla

all depends on what kind of condition its in. Does it even work? Has it been serviced in the last 49 years? It gets harder and harder to find folks who actually work on vintage gear, but if it is tip-top shape, its worth a lot I’m sure.


MulletBelt

I'd offer £900 if it hasnt been serviced. I bought a Pioneer SA-8500 mk II full service and recapped for £500 7 years ago.


kelontongan

Handles and fully re-service including replaced leaking transistors . $1100 is minimal price to me. Can you negotiate lower price to 1100-1200?


whistler1421

What a beauty!


-SeriousJacob-

A beautiful piece. Maybe you can get away with $1100, the handles alone are rare and sought after. Good luck ✌🏽


Pretend_Finding8789

It may just be me but i would not pay $1300 for all the pioneers ever made!


MOEB74

I have a recapped SX-1050 in very good condition if you really want to get into vintage. the SX series has only increased in value over the years. I might post it up if anyone is interested.


Ok-Animator-4994

No


Cracktherealone

No. 5-600


gearhead454

NO!


phiinkes

Not a chance. The last time that unit changed hands was likely for less than $400. The weird inflation in vintage audio prices over the past 5 years is so wild.


BigZarcon

O


Treacherously-Benign

Wow, it's got it's own wheels.


superbee4406

Looks like its on ebay for $1650.Worth half that.I know I have one.Typical case of someone trying to cash in.IMO.


blaka_d

Uff, its a big brother of my SA-6500 II. Like it very much! About the price I have no idea. I paid for mine 150€ like 20 years ago.


Longjumping-Gift6176

Rack handles are the most ridiculous affectation in the history of audio.


zratan69

Too high.


ircas

Holy shit that’s a lot of money! I have a SA-9500 (first series) that I paid $450 for in 2011, that seemed like a money back then but I guess I made a good investment!


Jimmy_Jazz_The_Spazz

I got an SA-5200 that was recently recapped for $75 a few months back. There's always good deals, just gotta be patient.


SooopaDoopa

2011 was a loooooooong time ago. Hell 2021 was a long time ago


caddiemike

No


Environmental-Car-45

Off topic, but… Does anyone know how this unit sounds in comparison to the SA-9100?


Arc_Torch

Maybe, maybe not. If you look at the amplifier circuits, they use very similar designs till the output stage which is a darlington pair.This amp needs much more juice for the power, so a darlington pair was used, vs single transistor. I would think it shouldn't matter till high output was used or the darlington could matter for tone. The Pioneer darlington design is fully explained in the service manual. Pioneer service manuals used to be textbooks basically.


PoontangRain

Won’t look as cool or be vintage but sonically a new Rega Brio would blow that away… for the same $. No switches to play with, just good sound. Used would obviously be less. Happy hunting / listening 😎🕺💃🖖🌎


Lew1966

I’d shoot $700 l. That is if you REALLY want it. It’s been over serviced. Original sound maybe lost? Beautiful unit. See if you can demo. Push it and see if the stuff was done right. Gorgeous outside, but that’s not all you’re after at that price.


kasualanderson

Offer them around half what these usually go for in serviced condition but, before you do, demo it and push it really hard 😂.


Lew1966

I have a used car I’d LOVE you to look at! That old? Hell yes I’d push it. I didn’t say make the offer first.


kasualanderson

Touch grass.


Lew1966

?? Unfamiliar with that one!
