This is the tube for guys with early 70s Marshalls that are known for high plate voltage I have a 72 super bass with over 500 plate volts and this tube can take it I tried a well known popular tube that I wont mention and one of the 34s burnt after one gig I called the guys at tubesandmore and they were very understanding and I sent the quad set with the bad tube back and ordered the jjs and with a little eq twiking they work great thanks again tubesandmore.
