I was hoping to use my back-up amp (Hafler DH-200) while I sell my CJ Sonographe to provide funding for a DIY PASS amp build. Still undecided about which one that would work best with my speakers, but that is a different story.
The Hafler sounds very fuzzy and distorted, although the music can be clearly heard too.
I'll have to fix the Hafler before I can start on the Pass, and was hoping someone had a DIY board to just plop in replace whatever is wrong with it at this point. I'm very new to electronics and have just completed my first Tube Preamp after 2 years of reading and asking questions. Thanks to all that helped me learn from scratch. I didn't know what a diode was, now I do.

Just hoping for some kind of update on this project as there are lots of experienced solder sniffers on this board.

Bump for any news?

Has anyone made more progress with this? I need a new PC-6 board, and I am going to make my own (toner transfer method, or use a sharpie, and draw.) Unless there is a mod that is cheaper than Musical Concepts, I'm out of luck unless I make a new PCB.
