Arran, thanks for the reply. Yeah I've seen them decrease with heat, but never permanently. I can't tell what the value is on it. the body is black, one of the ends looks like brown, but also looks like the body may have been painted black after the fact. No dot anywhere that I can see. Also this is in a bias circuit on a 6U7 that only draws 10ma at 6 volts. Don't know that that would cause an overheating problem. Anyway it's getting replaced. But something is pulling the B+ down about 70 volts in this chassis.
