Hi Beoworld. I am restoring a  Beomaster that has been in storage for a while I  realised the output section wasn’t connected to the heat sinks with the two brackets. having fixed this I am now getting a steady 10mv from the output resistors. problems this unit now has are: a very discorded phono 2 section in all channels. Not audible. Tuner section not working. No indicator lights. also a damaged trace on board 7 see attached pics.
