these are very well made reliable tubes that will take more abuse That most EL34 's because their ratings are much higher. Be careful not to over bias... a pair of these in push Pull operation can produce up to 70 watts...When I have used these I bias them to 60%-70 % like any EL34 and forget about it.

I am very pleased with these tubes. They are replacing some Svetlana EL34's that are still within spec from the '90's in a hi-fi (The Svetlanas, no longer manufactured, now go for big bucks.) These new KT77's IMHO are better in every way.
