Yeah the brimar is a nice option thats a little cheaper than a Mullard but somewhat similar sound. The Mullards have to my ears a characteristic "golden" kind of sound, if that makes sense. Kind of bumped up in the mids a bit, .... not a super accurate ruler flat responce like telefunken. The highs are usualy correspondingly slightly recessed, and in some amps .... perfect. Although as Myles would probably tell you, these tubes can be all over the map depending on the gain/output etc. The only answer ive found for NOS is to accumulate a bunch of different ones and swap till ya find the "magic one". They all vary quite a bit from era to era, and with diffrerences in construction. So far for most of my amps V1 is either an Amperex-Holland ( "champagne" ) or Mullard ( " golden" ). The Amperex, if you can pony up for a good strong one, is probably my favorite of all 12AX7's, it goes towards the Telefunken accuracy and power, but has just a tad of the mid warmth too! Good hunting!!

If you can go NOS thats the way to go. But if you're sticking to the options in your post, go with the GT12AX7M. It's a good strong tube. and it's warmer and a bit darker than most of todays offerings. Very full sound.
The JJ ECC803S is another nice fat, round sounding tube, although there has been some reliability issues reported on this forum. Go to www.dougstubes.com/. He'll make sure you get a good one, and the price is nice as well.
As mentioned above, experiment until you find the one that you like.

Thanks for the tips guys...Its interesting all the options you can have with preamp tubes...Unfortunately, it is impossible to try them all and find the best one...too exspensive...after all Ive read I went ahead and purchased the GT 12ax7m...We'll see...

GuitarZ: They say you should be on the same page about kids before you get married. I really think you ought to talk about expectations on outdoor Christmas/Holiday lights. That could have been a game changer.
