Sorry just want to get this nailed down my head is spinning as in who's on first
Well I was inspired by John Connelly :dbtu:
I looked up the pinout for a 6U8A tube and the heater is on pins 4 and 5
So I got my meter out and checked for continuity for those pins on the tube itself and then the socket and that seems to work
Yes, that is how they are called out, clockwise when looking at the pins from the bottom. Pin 1 is to the left of the gap (or locator 'key' when they have a plastic base like 6L6).
Usually we are doing any measuring from the bottom side of the socket, so it makes sense to designate the pins this way.
