Tom Mobley Posted November 22, 2009 Share Posted November 22, 2009 NOS Mullards are my favorite for pre-amps. Don't think you're going to find them at the shop. They're oriented toward guitar amp stuff. The tubes Mark installed originally are high quality, better than anything you're going to find at that place. search ebay for NOS Mullard 12at7 and 12ax7, get an idea what's out there.

tigerwoodKhorns Posted November 22, 2009 Share Posted November 22, 2009 I think that we are talking about the Terel here. I have used these two combos with great sucess: Mullard M8162 12AT7's with a GE 12AX7 "longplate" or "backplate" or something like that from the late 50's. Really nice and much better than the stock setup. Here are the Mullards: http://cgi.ebay.com/12AT7-ECC81-CV4024-M8162-Mullard-Tube-Match-Pairs_W0QQitemZ380176666907QQcmdZViewItemQQptZVintage_Electronics_R2?hash=item58844b911b Price is the going rate. Quite a bargain compared to some Amperex tubes that I have bought. I also have on loan from a good friend: Brimar 12AT7's and 12AX7's. Even warmer than the above. Very nice combos. I also have some miscellaneous RCA, Realistic and GE tube and the Electro Harmix tubes that came with the Tercel. Quote Link to comment Share on other sites More sharing options...

Don't forget the single 12AT7. I think that the TubeDepot had one for $30. Quote Link to comment Share on other sites More sharing options...
jazzbeq Posted November 24, 2009 Author Share Posted November 24, 2009 Received mullard, from canadian tubestores, no custum and quick shipping, will wait 15 hours to let them adjust, but so far, so good. Brendel on beethoven sonata,sound very acurate.... Quote Link to comment Share on other sites More sharing options...
jazzbeq Posted November 27, 2009 Author Share Posted November 27, 2009 very satisfy with my mullard, thanks all! Quote Link to comment Share on other sites More sharing options...
garymd Posted November 27, 2009 Share Posted November 27, 2009 No tube is more important for phono than the 12AT7 in the V1 slot. After much tube rolling, a vintage Telefunken ECC801S changed my audio world forever. The 2 shown here are slightly newer than the original I have in my BBX which came in a similar but non-colored box (still sealed) but I bought 2 just like those shown for about $125 each as backups. I think I'm probably set for life now. Quote Link to comment Share on other sites More sharing options...
garymd Posted November 27, 2009 Share Posted November 27, 2009 BTW - My favorite 12AX7 was an old Amperex (Holland) that died on me. I now use a nice Telefunken that is slightly less detailed although it could just be in my head. There really isn't much difference. I'd like to try a mullard some day if one happens to show up at my door. Edit: The 12AT7 doesn't need to be a match at all. V1 is the important tube. Any other decent 12AT7 will be fine in the other slot according to Mark. I put one of my spare mega-expensive Telefunkens in just to see and I couldn't tell much difference between that and what came with the unit.

jazzbeq Posted November 27, 2009 Author Share Posted November 27, 2009 Agree, i have amperex 12ax7 and pair of at7 amperex, but one at7 is microphonics [] this is why i turn to mullard Any way to dimiinish, microphonic tube? because at low level amperex sound good too....

The tubes Mark installed originally are high quality, better than anything you're going to find at that place They've actually moved into more guitar related tubes and gear, but they have a lot available.They have Mullard, Siemens, etc., and their prices aren't bad.

Just unpacking the Blueberry after a long hibernation. I think I have one of those Tele 12AT7.... but where.... hope I didn't throw that box away!

gartenman Posted November 30, 2009 Share Posted November 30, 2009 you just can't go wrong with any tube made in britain, holland or germany during the 50-60s and some 70s....mazda tubes (when i heard mazda tubes i first thought japan) made in france are nice tubes also...

gartenman Posted November 30, 2009 Share Posted November 30, 2009 brent jesse at audiotubes.com has some brass dampening collars to put on tubes that could fix your problem with the microphonic tube Quote Link to comment Share on other sites More sharing options...
gartenman Posted November 30, 2009 Share Posted November 30, 2009 did you get a 12at7? Quote Link to comment Share on other sites More sharing options...
jazzbeq Posted December 5, 2009 Author Share Posted December 5, 2009 i don't know, if this question is asked to me, but yes i get 12at7 and they sound "superbe" and thanks for the brass dampering, might work, but someone said that v1 is the most sensible, i could switch them, v3 to v1 and viceversa! bye Quote Link to comment Share on other sites More sharing options...
