JJ Electronic T12AX7SJJ Amplifier Tube

Matched my tester ,good tubes

As a tech it is so much better to have them tested and marked for equal gain. Tube buying can be a pain but getting like this makes my job a bit easier

Van Halen

I usually buy Solvek brand…I think I prefer these now. I put them in my 5150 stealth amp.

Simple tube replacement did what 120 bucks of bs 'repair shops' couldn't do.

Fixed a signal glitch - off and on - in the gain channel of my JMCMarshall 600, while
two repair shops hit me for a total of 120 bucks and didn't take car of the
problem...

JJs always sound good!

This set seems a little weak. Still decent tubes,

JJ's 12ax7

Good clean gain on these. No frequency loss either.
I am running these in my SWR 350x & 550x bass power heads.
