Which Preamp Tube is Phase Inverter on Tweaker ?

[Cindy]

Hi!

The title says it all.

I have looked a bit and did not find the answer. I have a Tweaker and want to experiment with preamp tubes as I have some from a THD Univalve that I no longer have.

I was told that the phase inverter tube should be a balanced tube. I have one and want to be sure I place it in the correct place.

Thanks
Cindy

The Egnater website has a lot of the tube charts on it. Go into the section on the amp and look around there.

The PI is almost always closest to the power tubes.
