re: AU-D11

The eu production model is different from the unit in the service manual. R63 and R68 (10K) are replaced with wire bridges. This lowers the output voltage of the psp to 52/54 volts. This introduces aproblem with the output transistors Q31 and Q40 getting really hot and dropping out after a couple of years. Replace the transistors Q31/Q40 and Q33/Q42 with MJE15032/MJE15033 and the wires bridges with 6K8 resistors. The amp can handle the increased voltage and the transistors wil live a lot longer.

forgot the rating, must be a 10+ on sound quality, build is a bit less !!!
