    Hello all! Hoping to get some help from the community. Just picked up some Cerwin Vega D5s very cheap. Couldn't resist the 12 inch woofers. Foam surrounds are shot, and speakers are dirty, looks like they spent some time sucking up water on the bottom few inches. But cabinets still look...

    Basic recap and restore BOM parts list on Kenwood KA-4002 integrated amp

    Performed a recap and basic restoration on a small Kenwood integrated amp KA-4002 and it sounds great. The KA-4002 has a cap-coupled output, so it has a warm sound kinda like tube gear and very much so the "1970's vintage sound". All electrolytic caps and "noisy" small signal transistors...

    Sansui 5000A low level static

    Some time back I got a Sansui 5000A in trade...it had one blown channel. I thought I might part it out... I opened it up and wow, you really have to admire the 5000a build quality. I fell in love, so much so that I went all out and cleaned every single solder joint and recapped every...

    I've had a Sansui 1000a for some time that I've been afraid to turn on because of old caps. I've decided to send it to them for a cleaning and recap. They said that it'd be a three month turn around on the project. I can't wait to actually get it back and put it through its paces (without...

    Marantz 1060 recap fail.....?

    Hi All! It's been a while since I've worked on any pieces, but here I am elbow deep in a cherry little 1060 amp that I found recently.

    Time to recap Marantz 2230?

    Hi Everyone. I had recently noticed a drop in sound quality from my Marantz 2230, perceiving it to be weak in both bass grunt and treble clarity. Sure enough connecting the pre outs into my Rotel RB980 power amp made a huge all round improvement in sound. The 2230 is an early model from 1972...

    How long do capacitors last?

    Apologize if this has been discussed ad nauseum, but I was unable to find this easily in a search... How long do capacitors last on average? I have a pair of Polk Audio RT-400 speakers that are circa 1997-98. Are they something that might be worth re-capping, or are they not old enough yet?
