Tube ---- Ei 12ax7


Does anyone have experience with these tubes?

I have a Jolida JD-100 and experimenting with tubes. I think I want to try these tubes next, but before I plunk down my cash for these bottles I thought I might ask for experiences or opinions.

So far I have tried.....

EH 12ax7
Vintage RCA 5751 triple mica black plates
JAN GE 5751 grey plates

Its somewhat of a tossup right now between the RCA 5751s and the EH 12ax7s.

The RCAs give great bass (for a tube) and smooth dynamic sound with good seperation.

The EH 12ax7s give awesome mids/vocals with a soundstage that goes to the neighbors house, but they are a little bass light.

Any and all inputs are kindly appreciated.

Since some of you may still be using this tube, I'll mention that Ram Labs carries them, the pre-war Yugos and as usual very well tested for noise, section matches, etc. I use them in my Music Reference RM10 without a glitch, in that application I just use the standard grade, quiet enough in an amp driver stage, but he also has them suitable for phonostages.
