Thanks guys for the input.
I understand that you will reduce the life of your tubes at lower voltages (below 90v) but does the lower voltage have a negative impact on the life of the OT or PT?
Using a variac when Metro Friedman is in 90v mode?

Again, less voltage, more current.Velva wrote:Thanks guys for the input.

check transformers temperature. if it's bigger than before, but not so much, don't worry, but if the transformers get really hot, increase the voltage.

On an Metro Friedman, I'm thinking that maybe one could hot bias (80ma) the amp in regular mode so that you could tweak it to taste with a variac? On variac mode you could just leave it at the bias setting it normally runs at?
I think that would work?? Give you more options?
