JJ Tesla KT77 tubes

I just put a pair in my Jcm 900 and think they are absolutely amazing. They greatly improved the tone of my amp. Anyone using el34s and looking for new tubes, I highly recommend them.

Peace.

They have a bit more in the way of balls than the EL34s. I'm opting for them over mullards when i get my QR. Great tubes...
