Thanks Steve. I'm going with 3900 ohms. Resistors (this 3.9K plus a 68K, 1 watt to replace the 70K resistor) have been ordered from Mouser.

Russ, the only problem with putting resistors inside the ceramic tube is that then you lose the ability to attach it to its mounting brackets. It depends upon a very long screw, with bolt, to hold it in place.
