Hi: Wondering if there are different schematics for the UREI LA3A mine does not have a bias pot. Bias voltage is 24 volts (should be 13). New T4B but no compression. Need some help! When I turn up comp pot, it pegs meter to the right and I get hum. I put the old t4B in and took off cover and turned out lights and it seems to react to light. I can hear a level change. When looking for ac voltages on T4B I don't find ac voltage like schematic says. thanks!
