The sapphire amp is done. I ended up building an external power supply, not enough room in the hammond to put everything.
I had overheated Q3 on one of the boards and the DC output was at 8vdc! luckily I always check offset before I plug headphones in.
Ended up replacing it and it works fine..
I had originally wired the chassis for dual mono output into a Y harness back to stereo.. then my friend suggested that i wire it directly for stereo.. no sense in spending time on the harness..
upon rewiring, the left channel refuse to work.. i didn't even touch it..
i must be jinxed
