Interesting. I also found very few (if any) high valued resistors in these sets that were bad. I did however find some low valued ones (< 1K) that were way off.

It does have a different current of the filament, something like 150 ma instead of 300 ma. So if I use it, I will have to bridge the filament with maybe an 18-20 ohm 10-watt resistor when I use it for testing.
It was suggested that this CRT would be good for a gardening show or horror movie  |
Very cool
You might get a kick out of this thread I posted a while ago. I tried hooking up a 7VP1 and a monstrous 12FP7 to a VT71.
