This is an integrated classic dual mono Audio Sector LM3875 chip amp housed in a vintage Pioneer SA-600 amp case.
Integrated, because also inside is a Pass Labs B1 buffer pre-amp.
This amp has a great vintage Pioneer look. Transformers are (2) 22-22V 160VA Avel Lindberg toroidal.
It has 2 inputs and A & B speaker outputs. A posts are quality Dayton Audion posts. Currently the B speakers are disconnected because I didn't use them enough and I wanted to keep the output leads as short as possible. You could easily reconnect them if desired.
No tone controls.
It has been in my main system for about 2 years and it has run very cool, dead silent and performed flawlessly.
I'm asking $199. Buyer pays shipping. I accept paypal only.
Thanks
Brian

Sure thing!
By the way, I didn't sacrifice a working Pioneer amp for this project. It was on the fritz and I liked the champagne look of the front face. Very classy.
The heat sink for the chips is a section of 3/8" thick aluminum angle, and it does its job well. This is a very cool running amp.
I've seen amps that were wired a little bit more tidy than mine, but I've seen some that look like a bird's nest too.
However, you can see that attention was given to short wiring lengths, separation of power supply and amp side. I also made a reasonable attempt to twist signal and AC leads. But like I said, it is dead quiet, so the wiring is adaquate.
Cheers!

it looks very nice!. Too bad you never try it with bigger power supply
Those 10uf caps are way too small. I build these kits long time ago and the sound was FLAT using those joke 10uf caps in the power supply...as soon as I put a few 10000uf the sound came alive I bet, if you try using at least 10000uf per rail, you will not sell it

The reason I'm selling is that I have 3 amps (not much by some people's standards) and the other two have sentimental value to me. And I need some money for a speaker upgrade.
I wouldn't be too disappointed if it didn't sell though. = )
