In Reply to: RE: 12AT7-tubes for Preamp and Poweramp :JJ vs Telefunken NOS posted by email@example.com on February 28, 2017 at 00:09:35
I've have never tried the Gold Lion 12ax7 but I have used a number of their other tubes. So far ALL have been excellent. The smaller preamp type tubes do have that warm full bodied, and may had a little richness and texture, feel to the sound.
I was quite shocked to hear their 12Ax7 actually sound better (full bodied, warm and good bass) then my highly coveted RCA long black plates that now sit in a box.
I would like to add this. I'm finding the GL, in general seems to be a more balanced tube. Meaning good bass, good treble, good midrange, etc...Nothing out of proportion.
what gear are you talking about. Because some times that IS an issue?

Hi, airtime: My preamp and poweramp were made by AVA which specified using a lower gain of 12AT7 tubes . As you have mentioned the Genalex gold lion 12ax7 is that good/excellent; I assume their 12AT7 should equally be as good ,hence, I am so tempting to get them Thanks for your info and suggestions
I have an AVA FET valve CF preamp and 600R power amp. I replaced all the stock JJs
with Mullard CV4024 (12AT7) and Mullard CV4003 (12AU7). Everything improved over
stock including much better midrange and highs. This combination will give you a nice touch of warmth without going too far.
I've been researching AT7s for my amps driver stage and see in the archives here it's Jim McShanes favorite, BUT, one must be careful to get them tested for microphonics.
Some UK adverts for the tube cite it's construction being good for eliminating microphonics so I'm not certain what's what. I do see that NOS, sealed box CV 4024s go for around $70/pair. Not too bad.
Ever try the GL 12AT7 (B739)?
Hi, FenderLover; I have posted GL 12AT7 yesterday, so far no response yet . I am so tempting to get them .(I am a Bass-fanatic, I thought TFK might sound too-analytic for me and hence "lean-sounding" ?)
Prolly one of the best new issued 12AT7. For NOS, if the TFK was too lean-sounding... maybe hunt for a nice NOS Philips/Miniwatt or Mullard ECC81?
No, but if it's anything like their 12ax7 B759 then I would grab a bunch of them.
