    Technics SH-9010 Equalizer Recap—a few questions

    Recently I acquired a Technics SH-9010 parametric equalizer to help compensate for the low frequency loss in my open baffle speakers. This 1978 EQ is in quite good shape. It was advertised as "serviced", which seems to have been done well, but was limited to cleaning and de-oxidizing switches...

    Sansui 1000A Repair

    Hello there, I recently inherited a 1000A tube receiver, I have replaced all the Elna and Suzuki oil caps, and have extensively cleaned all the controls. The recap / Deoxit restored proper function to a lot of the tone controls, inputs, balance, and other functions. However I have a weak right...

    A (nearly) full KLH Model Four restoration guide

    Close to a year and a half ago I purchased my first pair of KLH Model Fours. They were in working order, but not perfect cosmetically. I had read all I could find on AK, as well as the rest of the internet, so I already knew that they were pretty well-regarded, and semi-rare. I was in the midst...

    Yamaha A-1 score (possible resto)

    Hi guys, managed to score a Yammie A-1 stereo amplifier for the not so hefty sum of 110,- dollars. It was a bit of a gamble, the seller didn't have any information regarding the state of the amp nor did he post any photo's. His asking price was very reasonable so i made the jump. When it got...

    Repair and Upgrade of a Previously Recapped Sansui AU-555A

    On the bench is a Sanusi AU-555A that was sent in by an AK member for repair and upgrade. The background on this unit: the owner had this unit recapped (approximately a year ago by a tech local to him), but was less than satisfied with the results. Aside from the lackluster sound following the...

    Need advice in recapping old electronics

    Kenwood KR-77 with a weak left channel

    What would you recommend I do with a vintage Kenwood KR-77 with a weak left channel. Should I recap the entire unit? Is there another potential source for this problem that might not require an entire recap?

    Technics RS 1500 Rewind Issue.

    I have a Technics RS 1500us. Rewind all but stalls out near the end of the Rewind process with 7" and 10.5 Inch. Fast Forward works fine. I've swapped the Supply and Take-Up Reel Tables to see if it's that and to eliminate the Reel Table Board was possibly the issue. No change. I've recapped...

    Pioneer SA-8500 Recap/Rebuild/Restoration/BOM

    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...

    Kenwood 700M - replace filter caps?

    Hi, I recapped a 700M a few years ago. I left the original power supply filter caps in- the big ones. I've sometimes wondered if I should spend the money to replace them, and just to complete the job. Looking at $100 minimum, probably. If the current ones seem to work fine, though they're...

    short hum at startup of recapped NAD 3120

    Hi all, I am pleased with the recapping I recently did of a NAD 3120. Compared to the previous Quad 33 preamp I think it sounds a bit more open and defined. There is a small problem though. When I startup it will produce a short hum like sound in both speakers even at minimal volume level. The...

    CR-2040 : recap experiences ?

    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...
