Members tonaldeath Posted January 13, 2011 Members Share Posted January 13, 2011 I've always used 12ax7 tubes in my amps. I'm wondering what making the switch to 12ay7 tubes will do. My goal is to squeeze a little more clean head room out of a 25 watt two-channel amp. It is sort of a 5e3 with a bit of jtm45 squeezed in. I want more headroom, but I still want to be able to go balls out with my fuzz factory, and my OD pedals. Will 12ay7's allow all of this? I've heard you can put one 12ay7 in the 1st position... Would you guys recommend I do this, switch out all three, or just leave it alone? Thanks! EDIT: btw, the amp uses three preamps tubes, two power tubes, and a single rectifier tube. I'm using 6L6's in the power stage, and a 5U4 rectifier tube. Link to comment Share on other sites More sharing options...
Members ken361 Posted January 13, 2011 Members Share Posted January 13, 2011 they have less gain so it may work, also a 5751 is just under a 12ax7 in gain Link to comment Share on other sites More sharing options...
Members cratz2 Posted January 13, 2011 Members Share Posted January 13, 2011 What is the actual amp? I mean, what circuit is it based on? Going to an AX7 to an AY7 is a really big jump. There are three or four steps in between there. The 5751 is mostly a smoother, less bright tube compared to most of the others, but you don't lose much gain vs an AX7. I'd probably get an AT7, an AU7 and maybe an AY7 and just try them each out for a day. Link to comment Share on other sites More sharing options...

Are you saying to just get ONE of each and try them in the 1st position, like I had mentioned? Link to comment Share on other sites More sharing options...

I would definitely try even a 12at7 before you go the 12ay route. may be exactly what you're looking for. try to find some tasty nos tubes for it :] Link to comment Share on other sites More sharing options...
Members tonaldeath Posted January 13, 2011 Author Members Share Posted January 13, 2011 Casey, forgive me for being too tired and drained after a hellish day to properly decipher what you're saying... Did you mean that you owned a Frenzel Deluxe Plus? IF so, did you try the 12at7 in the 1st position? Link to comment Share on other sites More sharing options...

Members charveldan Posted January 14, 2011 Members Share Posted January 14, 2011 Try a JAN 5751. An AY7 will pretty much neuter your amp. Link to comment Share on other sites More sharing options...

No I did not try the 12at7 in it, as I didn't have any problems with it that would warrant using one, but I've gone the 12at7 route in just about every other amp I've owned, and it's almost always an improvement. My whole point though, was try the 12at before the 12ay. Link to comment Share on other sites More sharing options...
