It's been a few years since I have worked on a radio.
Currently working on a zenith for a boss at work.
With the chassis flipped up side down, how does the pin out on the vacuum tubes go?
From the tube alignment notch clockwise or counter clockwise?

Clockwise from bottom counter from top....a good visual aid is a NOS replacement socket with numbering... whenever you find yourself questioning really you can pick it up and reaffirm things.

(Looking from bottom) go clockwise from the notch, with first pin as 1.
