Re: A little Hot

by EZS -

Apparently with my bias probes in place I got a B+ of 474 which is a touch high, especially looking for classic 2204 tone. Once I removed the probe sockets and measured again, I read B+ 408 which is perfect.
I confirmed this twice. I have no Idea why plate voltage would give me different reading with the probe plugs in place, but they did.
I emailed admin to please remove my previous review.
