42 PT-10 pilot light
#4

I considered whether the candohm might be acting up, although the two sections (40 and 80 ohm) measure 42 and 84 ohms when cold.  I wondered if something was happening when it got some current on it.  That is where I will try first, as I've read other places that these can be problematic,  but thought that since they measured in tolerance that it would be ok.

I looked at the filament string and it looks ok, wasn't touched in the cap replacement.  Also have looked for any other shorts to the chassis and solder blobs, but haven't found any.  The lamp socket and wiring also look fine.

I'll order the power resistors and report back if the candohm was the culprit.
