C4S Board Voltage Fail

Yes both go back to 0 ohm.

You'd have to have a shorted tube for this to happen, and you should be able to measure that short by using your meter to check for continuity on the various combinations of pins 2, 7, 3, and 8 (pins 2 and 7 may read as shorted, which would be normal, but the rest should be open between all pairs).

Checked continuity on pins 2,7,3,8. All pin combinations read open except 2-7 which you said may read as shorted. Does this mean that something is wrong with the socket ?
