    I have most of the test gear needed just not any real voltages to go by and a few differences in the schematic I am going by this one

    3 watts am 8 sbb adjusting drive level does not help. mine seems top be the same as Bob's board from the other thread. I read 36 volts on the collectors of TR 6 & 7 in standby that sound right?

    I was trying this mod but mine is a bit different did not want to make a mistake. Also the 4 pin jumper i am guessing it goes on the top 2 pins.

    I can not find a schematic for it. I have soldered up those joints after the pic was taken i replaced all of the transistors in it. I have hit the wall on this one

    Be nice if they gave you voltages on the schematic such as TR9 I was trying to follow Bob's bias fix but mine is a bit different
