Product Reviews
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.
After the transformer was installed the new EL34's lookin' good so far
Great JJ el34 tubes. They arrived quickly and well protected in their package.
