My early 900 50 watt head is not as loud as it used to be. It has new power tubes and has been biased. What could be the issue?

Hello Rob,

It is very hard to diagnose without seeing the amplifier, it could be a faulty resistor we would recommend that you have it looked at by an engineer.

 

Kind Regards
