Zenith 7-S-240 Eye tube question
#16

Have you rechecked the 1M (R15) resistor in the eye socket between pins 2 & 4.   Also pull the eye tube out and make sure there are no shorts between pins, except for 2 -4.   I'd also trace out and verify the 6T5 socket is going everywhere it is supposed to.

Other than the eye tube not closing properly, how does the radio perform?  Does it seem to pick up normal stations like it should at a normal volume?  Do you have to turn the volume down quite a bit going from a weak to a strong station?  Something is keeping your AVC voltage too low.

I hate to say it, but I'd double check any capacitors, resistors, or anything else you may have changed against the schematic for wiring errors (it happens to the best of us).

Hopefully Terry will take a break from his 42-854 and offer some more insights.
