I have an Origin 20 Combo and I just bought a new set of tubes, and I was wondering if i have to take it to a technician to bias it, or even if it needs to be biased?
I wanted to change the power tube in my DSL1HR Head. Will it need Re Biasing ? or I can go ahead and just swap the tube and no problems it is good to go.
I recently bought a new DSL40CR. Great sounding amp! Great tones! I am noticing that the low end sounds a bit flubby. I was reading in some forums that this can be caused by improperly adjusted BIAS. Can anyone direct me as to what the mV for each left and right tubes should be set to?
