Ge 12t4

Well, if they are to be 75 ohms, and they read 2.5K ohms, and they are in series
with the filaments, then the current will be very low, and should not be a problem
at all if you fire it up..... tubes will not lite.... If it's a thermister and they drop
like said, when they get hot, then at 2.5k they are a pretty good safety cushion
for the tubes.... Better than 850..... might be smart to leave them alone.....?

Looks like a tv I just got done working on for my brother.... Bad electrolytics,
I saw those 2 resistors in the string, didn't even give them a thought....
Filaments come on slow, so I guess it's working as it should.....

Yeah, I think I'd give them a try as is. Then verify some tube filament voltages after they warm up. I'm not sure if the CL90/resistor combination would give you anywhere near the desired warm up delay.

Just for fun here's a picture of the Workman sub, looks like a dead ringer for those in your set. I'm not sure how these hold up with age setting on the self. This must be pretty old stock, considering it has the GE number, as listed in Riders. You can have this one, but who knows how hard it will be to find another?

Thanks for the offer, but you are correct it would be very difficult to find a second one.

When I checked mine they read 400 ohms each when cold.
