I tacked in a 1N4007 and CL-90. I also disconnected the CRT and stuck a 5 ohm resistor in it's place just in case I got something wrong.
I turned the set on and the filaments slowly lit up to the normal brightness
I reconnected the CRT and it works just fine. The CL-90 getts a little hot - maybe 2-3 watts. Certainly better than 20W

I also tried a CL-80 (slightly lower 'ON' resistance) but didn't notice much difference.

Now, on to the selenium rectifiers. I checked B+ with them still in the set and it's only 213 volts It should be 255!
I'm really curious to see what effect getting B+ up to the proper level will have.
