I have a mess of old Neotec NT500 tubes. the chassis where an absolute dog turd, and are all toasted. As such, I have a half dozen NT500 tubes cluttering up my warehouse.
I'd like to find a Wei-Ya (or whatever) compatible chassis to replace the original chassis. I don't have an inductance meter to test the yoke. Would anybody know what it's H-V value is, or a part number for a chassis that would work with these tubes?
