I got this beast of an amp off a guy to sort out for him. The wires to the speaker outs needed resoldering back on, he told me it was 80 watts class a and great sound quality

Im more a japanese than a chinese amp guy, and my first thought was this is junk

Anyway I fixed it up but I want to adjust the bias on this thing, bought a manual from acdc manuals which turned out to just be schematics , they gave me a refund for purchasing and said that basically the diagrams are all that there is out there.

Its putting out 45mv across the speaker outs , I threw it on on some test speakers with preamp and cd player, and it actually sounds very good to me

Anybody know procedure for setting idle current and offset bias on these? it would be a great help
 
Thanks for the lead. I emailed them and they said that they never dealt with this amp before and that Chinese manufacturers never provide repair procedures.
I like Japanese built amps even more now.
Will just have to keep trying to find someone who has experience with Jungson
