Hello I am looking for a schematic for Braun PQ 20.
I have a problem with this amplifier.

http://ampguts.realmofexcursion.com/ads_PQ20/

http://img1.abload.de/img/braunpq20o1m4.jpg The connector who is in red underline is the problem. When he is connect the amplifier doesn´t work. If it is disconnect the amplifier goes on because the measurement shows 0,73A.
The Transistor in the power amplifier (2SC 3281 and 2SA 1302 has got -30V and + 30V)

Thank you for help.

Regards Jörg
