I know that... I am referring to the polarity issue. ie... does red go to V4 or V5?

Black to V4, red to V5 -- or at least that's how I wired one into bluze81's JTM45, with pics to prove it to myself........

Awesome... Thank you Flames, and thank you Bluze. I'll have it wired up in few minutes.

Well, for whatever reason, mine is opposite that.

Brian had responded to an email I sent him asking the same question, and said "If you have wired the amp so that the PI 82K resistor feeds V4 then it's Red for V4."

It is indeed red to V4, and black to to V5... on my amp anyway.
