3 123.7

Timmy, on V21 do pin 2 & 3 really have the same voltage on both pins....?
Can you investigate this ? Can you check resistance compare to Sams
on these pins? Possible short in the socket, or internal to the tube?

I'm not sure about R166, R167, & C116... Not sure what to do
with the flyback pulse at this point. I would be happier solving
the odd voltage stuff first & being somewhat sure those items
look like they are working.... If you guys want to pursue
the flyback pulse it's ok, I just don't know how your
going to test for it. But we could test for the tube
voltages with the tools Timmy has.....
Either thing could be just a tail
chase anyway....

I’ll check those pin voltages again does seem odd.
