Re: power amp tube blowout...fast help please
Some 6L6 tubes cannot take the voltage a 6L6GC can. Same for a 5881, they are all diferent tubes. Checkout KCA tubes and do some google searches. It's very confusing.
I would not use a 6L6B in any Fender amp made after 1960 and even some tweeds. It all depends on the voltages not only the bias.
