I've got a pioneer sx-3500 that I'm planning on recapping. This is my first time recapping anything, so I'm worried I chose the wrong capacitors for the job. Included are the values of the capacitors I figured out from the service manual on an Excel sheet, the service manual, and the Digikey...
Hi, I'm planning to completely recap my Sansui 9090 and wondering if anyone here has a list of all capacitors they used? I'm thinking of using Nichicon UFG capacitors but if you have other suggestion, please let me know. Thanks.
I have a pair of Dahlquist m905s and I’m going to replace the Vifa 6 ohm tweeters. These tweeters are no longer made and Regnar sells them for about $100 for one and they should be replaced as a pair. The Vifa are nice from Denmark but there has to be a more inexpensive comparable tweeter...
Just to keep everyone guessing, I only replaced the electrolytic caps in this Harman Kardon 330A instead of replacing everything I could desolder. ;) For those of you who just want to do a minimal recap and you have the matching 330A, then this thread should help find the right parts to return...
Had a few extra days off tied to this weekend & looking for a vintage rig to gift to a co-worker. Lo and behold there popped up a non-working SX-626. The pictures showed the pre-amp jumpers missing, so I thought this unit might just need some refreshed components. At pickup the previous...
Hi Everyone,
This is my first post on in the forum. I am now the proud owner if a Sansui Eight and would like to recap the unit. I've seen that changing out the trimmers and transistors are also suggested. Does anyone have a parts list that they would be willing to share? I noticed that the...
A few weeks back, I was eyeing this unit when a better deal popped for the AU-717 that ended up in my collection. This unit was still available after I finished my rebuild. I recommended to my co-worker BK (who is starting to get into HiFi and vintage equipment). Price was improved and BK...

(build details - list)
Completed this rebuild a few months back... just getting around to sharing the process (before I am too far away from it).
Not the easiest unit I have rebuilt / restored for sure. Not...
Picked up an older Pioneer AMP. It is an SA-900 with cap coupled outputs. Works but needs some love on push buttons switches (sticking) - I have them working albeit not ideal yet. The plastic housing was broke and they wouldn't latch. Working - but anyways, I just wanted to know if any of...
So, I definitely have the feeling of "what did I get myself into..." with my second recap project. The number of boards and jumper wires really has me wondering if I'll ever get this puzzle back together. I do have lots of photos and I labelled everything, separate bags for groups of fasteners...
Here are some current units that I snagged recently. Obviously, I have problem with buying stuff, but this is my hobby and I enjoy it very much.
I remember when I was ten ~1984 and my father brought home a used stereo for my room... someone he knew well had passed away and his wife gave to my...
While my tweeters are getting reworked, I was thinking about replacing the capacitors on my KEF Q15.2 speakers. The original ones would be around 20 years old - they are LICON brand caps. One is marked as 8.5 uF/50v and the other as 12 uF/100v. Anyone know of some good high-quality replacements...
A few days ago I picked up an SA-8500 that my neighbor left on the curb. Other than the fact that it's missing one of its feet it's in okay cosmetic shape. It does have some corrosion on the rear contacts, pre/main jumpers, etc., presumably from being stored in a damp basement or something, but...
I’m working on my first recap job. The “patient” is a SX-580. It was totally dead when I bought it. Found a coroded capacitor that had broken off. Got it working good with low DC offset. Was going with Nichicon caps, but I am a little confused about the different series of caps and what’s best...
I am tempted to recap at least the phono stage of CR2040 - there seem to be lot of caps in the signal path. When I recapped my KEF Cantata speakers, all caps were off by at least 15%, and smallest were off up to 300%.
CR-2040 probably runs hotter than the speaker crossover, so I would definitely...
What are your thoughts about replacing the 8 output transistors on a Pioneer SX-1250
Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8
Original part numbers:
Q1, Q2, Q5, Q6, 2SB600-R
Q3, Q4, Q7, Q8, 2SD555-R
Replace with
Q1, Q2, Q5, Q6, 863-MJ21193G
Q3, Q4, Q7, Q8, 863-MJ21194G
I am getting ready for a fulI...
I just bought my first SX-1250 from fellow AK'er roadie1 for $75, a big thank you to him for letting me have it at that price, the thread on finding it is here: http://www.audiokarma.org/forums/showthread.php?t=420677. It's in beautiful condition and a great candidate for a restore, all the...
