This seems not to be good start to start collecting RF amps, 2 first amps from germany and both are broken.
right channel has ,3volts dc and left 1v.

theres what i got from RF, hope it´s ok to show it here
With the black probe on the amp's main ground terminal, what's the DC voltage on pins 4 and 8 of U101?
What's the DC voltage on pin 14 of U2?
Sorry for 13months delay.
I took this to local tv/radio repair, lack of interest/no easy way out i took it back.
atleast there was no money involved to check this white elephant
U101 8 there is 13,8volts, -23,5v on PIN 4
U2 pin 14 there is 25,8 volts
