@steakster what do you mean by class A all the way? The amplifiers may actually have higher power in class A/B above what they are rated for in the spec sheet at class A.
Class of operation for Tube Power Amps
My understanding is tube amplifiers can be ran in Class A or Class A/B operation just like Solid State amps. MANY tube amps do not say what class they are running. If they don't say this in the specifications do you just assume the are Class A/B. How can you tell?
