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.

I use and find the recent production EI's to be excellent in all but two respects - they are not overly warm but they produce a very clean clear sound. They are not etched or cold sounding. The currect EI's are having quite a bit of quality control issues (best to buy more than you need, some will certainly fail). Older production grey plates are quite good, and usually fairly quiet. I have not enjoyed the EH's as much - reminds me of the sound from Sovtek 6922's, cold and uninvolving so to speak. Have not heard the RCA's or the GE's.
