Phase inverter

[axwielding1]

How important is it for a balanced phase inverter tube? And, does it have to be exactly balanced? I have a 5 star 5751 black plate triple mica, and tests 106/108. Is this close enough? Or should I get a perfectly balanced tube....
ax. :twisted:

If your amp has a long tail phase inverter design, it isn't important at all due to the fact that both sides of the phase inverter circuit are not equal as far as the circuitry is concerned.
