Been rolling in my Reeves 225 bass amp & found I preferred the Tung Sol to the Mullard.
Less gank on the upper midrange. I will be trying a few other brands as well.

Two Tung-Sol 12AX7 tubes were used to replace some old tubes that had low emission. These brought back the full-bodied sound the H-K A-300 was capable of. It sounds great now like it did when the amp was new.

I run a heavily modified, re-voiced Super Champ XD with a 12" Celestion 70/80, and it has a big, fat smooth & defined sound, and also gives jut the right amount of volume boost to the Champ, coupled with Ruby 6V6's in the power stage. The distortion has a softer, more British edge. Does wonders for my Strat and Tele, and brings out the fullness of my D'Angelico EXL-1. I can use this amp on louder gigs now.

Quieter and longer lasting than the JJ's. Everyone who has had work done in our shop loves them now. Our go-to 12ax7 unless otherwise requested.

These preamp tubes really brought the Monoprice 15 watt amp into a territory that only higher-priced amps occupy

Not only is this tube a ‘night and day’ difference to the Chinese clone which I was using, but also the amazing service, communication, packaging and ultra swift postage of Antique Electronic Supply, is exemplary. Brilliant in all respects.

The Tung Sol is a very warm and creamy 12AX7 with nice detail. We would suspect that you would get these attributes with the Vox.

Hi, all 12Ax7's are comparable with each other. This will work just fine.

What is the difference in gain and tone with the ecc83 and ecc803s (gold pin variation of this) and why isn't the gold pin listed as an ecc803s when it is on the box/label?1 answers

Both of these Tung Sol 12AX7's are ECC803S. They are very close but the gold pin will have slightly less gain in the mids. The ECC83 is a mid gain tube and will have less gain than a 12AX7 (ECC803S).

Absolutely. High gain preamp tubes combined with low numbered power tubes should provide your amp with earlier access to breakup.
