I have a SHP 3 amp and the output transistors are getting very hot. I
checked the bias voltage and they are over 100 mv and will not adjust.
Has any one ever had this problem.

Do not run the amp until you repair the pin connections on the plug to
the circuit board in the amplifier. They are failing leading to bad bias.

Here are the notes from one very large operator of Seeburg jukeboxes
back in the 60s and 70s
