It is quite possible you have a bad bias pot. However you're looking at the wrong pot. The 100 ohm pot is a hum reduction pot. What you need is a 50k multiturn pot. Check for bad connections first.

A word of warning here. There is nearly 1000 volts inside this amp. If you don't know what you're looking at, don't go in there. Find someone to fix it for you.
