AU-505 restore project

[ricksiri]

richardpp: thank you.

I finished up this re-capping/restoration. I had a couple of stumbles, but with everyones help, especially Hipocrates for his pics, i did it. Thanks again. I replaced all of the electrolytics as well as all transistors, including output transistors. I've adjusted the bias and internal offset. It's sounding pretty sweet right now out of my old KLH sixes.
I'm looking forward the next project.

Good work!
That's a very nice little amp

A friend says he has a Marantz 2215B, that I can have. He says it "doesn't work". Sounds like my next project.
I'll start a new thread.

Its generally a good idea to finish a board - then hook up amp to test. Alternatively you can find yourself with a faulty amp, but not sure when and where it happened.
