at7's in phase inverter slot

[ConcreteVampire]

Thoughts? I see mostly ax7's in new amps, at7's in older.(or recommended in older Marshalls due to the increased current)
A matter of specific design? or just what sounds good?

Electromechanically what gives when say putting an at7 in my VHT or Vintage Modern?
BTW...
The VM has a PPIMV as the stock volume. Effects there?

Thanks!

There's some really good info there

In the standard Marshall type circuit I like the 12AT7 better than all the AX7's I tried.
Even in the Trainwreck Express clone I just built, which is a very revealing amp, the AT7 just sounds creamier.
The fact that I use NOS Mullard 12AT7's (still somewhat cheap) might explain some of it.

I tend to like a 5751 better than an AT7 most of the time.

12AT7 is my favorite PI tube.

Yep ive got that exact tube in the VM right now. Will try it out today, along with an nos bugle boy, and a high gain matched jj.

After the Riffy posting debacle, I'm inspired to post now....
