I powered up the chassis, out of the TV, and it looks like the B+ voltage is only about 10 volts higher that what is specified on the schematic. So, I don't think a resistor is necessary.

The first two times I powered up the chassis, I had no HV. When I connected my meter to the HOT grid to check the drive voltage, the HV came back and has not gone away since. I suspect a bad solder connection and, tomorrow, I'll go back over my work in that area. The only voltage that was a little low was the HOT grid drive. The schematic specifies -23 volts and I'm only getting -15 volts. The other HOT voltages check fine and I have not yet checked the HV.

When I pulled the yoke, I discovered that it was a Merit replacement. And, what was left of the housing crumbled into little pieces.

Also, the aquadag coating is flaking off the CRT like crazy. Some time ago, I think I remember reading something about aquadag paint that could be used on CRT's. Is that so?

The CRT looks original; but, this set has spent a lot of time on the repair bench during it's life.

On sets like this, I wish I had one of those '50's era B&W CRT test tubes with the extension cables for the HV, CRT socket, and yoke.
