Re: tube/bias adjustment problem?

Does your amp have a rectifier tube such as 5AR4 or GZ34 or is it SS rectification? Sometimes when the rectifier tube starts to go, the voltages start to go south resulting in low bias draw from the KT-88. Be careful if you decide to open it up as the voltages can be lethal.
