Hi Gang:
I am restoring a Philco Model 51-537 Clock/Radio Model.
All the caps were replaced, resistors checked, and replaced when out of spec.
The radio worked, so I proclaimed it finished. Then I installed the pilot lamp, and it seemed to blow out at various stages...sometimes during warmup, after warm-up, sometimes after minutes. Icon_sad

.....the radio will still play good.
How do I troubleshoot this? The radio uses a 35Y4 rectifer tube , and the lamp is wired to pin 1 and pin 4. The lamp socket measured 10.6 VAC and 2.35 VDC when warmed up.
Any ideas out there?
Thanks,
Buzz
