Oh, I do. I have 2 mkII's and one mkIII. Frankly, they sound great and I can't hear much difference between them. They seem to play cleaner at a bit less than full volume. I use default filter setting .......

That is odd. I've been using them for years in a Dynaco pas. If anything, they are a bit fuller sounding than a regular 12AX7. Are you able to test them? .......

JJ EL34, KT77 and 6CA7 do sound different. But of those 3, JJ EL34 is the only one with 3 wire grids. 6CA7 and KT77 are both beam tetrodes. After all, KT stands for kinkless tetrode. Correct me if I'm .......

I have a few spares, and they seem to last forever. One has been working continuously for over 20 years and still sounds good. .......

Have been happily using a pair of Eric Barbour's SV811-10 monoblocks for many years. Originally, coupling caps were .47uf and when I did the later circuit modification (using a 6EM7 driver in place of .......

Posted by jblock312 on 2020-01-19, 12:42:26 (76.219.159.79)
Last week, one of the EL34's died in my ST70. They were JJEL34, the regular EL34's. I put in a set of Sino EL34B's and couldn't stand it. With my speakers, treble was beyond "sparkly" it was shrill. I .......

Posted by jblock312 on 2019-08-21, 16:43:03 (76.219.159.79)
I built a SE Fleabreeze amp that has 2 50C5 tubes and one 5751. Their filaments are in series with a 30R resistor to equal 120V the isolation transformer puts out. Probably a dumb question, but... Can .......
