SO, I got some 1W metal-film R's...and

Check out the CCF60 series from Vishay.
They are nice!
500v, 1% tolerance

Yes. they look nice. Now take a hammer a smash the epoxy coating to expose the resistor proper. Surprise

Looks like Tube Depot has misquoted the working voltage spec- it's 300, not 500. The often-used RN65's are rated at 350, FWIW.

Aleks, I must admit I've never taken a hammer to a resistor. What is under the coating?

[Structo]

Yes, do tell.

[VacuumVoodoo]

C'mon guys, I'm sure you can afford to sacrifice one resistor to satisfy your curiosity. Take one for the team.
I have no more CCFs at this time...
Hint: remember that X-mas when you got a present in a big box only to find it was a waste of space?

I used some of these cmf60. About the same size as 1/2 watt, but rated at 500v. Has anyone else tried these?

Yes, although not in high voltage areas like plate feeds.

350v should be plenty, right? so whats the good high voltage resister options to get?
