Bias current and plate voltage for Air Tight ATM2?
I've owned an Air Tight ATM-2 for a year now and twice a power tube has failed. First, an old stock Tung-Sol 6550 blackplate, which perhaps could not hold up to the modern amp. But, recently, I switched from reliable SED KT88s to the new Russain re-issue Gold Lion KT88s, and one of these tubes developed a leak after just less than 3 months use. A coincidence perhaps.
But it got me to wonder what the bias current and plate voltage for this amp are, as neither specification is published information. I've put these questions to two dealers and neither have been able to provide an answer.
I've also written AXISS, the distributor, to the same result--no answer.
Does anyone know the answer to these questions?
