How much does the 'phase inverter' affect my tone?

Excuses I don't need to refute any of this, I think your erratic behaviour on this forum speaks for itself I'm out of this topic - I wasn't even commenting on your thread really, just the gibberish comment. Peace

I have a few spare old Sovtek 12ax7's. I'll send you one if a want to try an older tube.

Thanks man, but I'll be right. I tried a few tubes that CAB sent down, none of them made alot of difference really, but I settled on one that seemed to make no difference slightly better than the other two. (? ?)

my old sovtek mig 60 didnt have a phase inverter

sounded like poo

you sure?

how many pre amp tubes in that schem?

i can find 2, my old mig 60 had two, and two power tubes, note on the schem it says "may not be in early versions...etc etc" its possible the Pi was'nt a tube and could have been some other desighn

I can find exactly one preamp tube

Single channel amp with master volume. Way i read it, V2 is is the preamp and V3 is the phase inverter...

Making V1 = ?

There is 6 triodes in that schem;

Each 12ax7 has 2 triodes in a bottle

so that would make it 3 12ax7's in total!!

Sounds like you had a hackjob mig60

oops, my mistake, V1 and V2 are preamps and V3 is a phase inverter.

Weird seeing an EL34 sovtek tho...

No worries, I just wondered if you considered the input stage different to the preamp stage. At least this thread is once again about phase inverters and tubes

That's highly unusual for this forum...

Anyhow, no, I simply didn't see V1 because my beer bottle was in the way And sides it's kinda hard to _not_ have a phase inverter in a class AB amp...
