[R-390] Need value of R235 from a RF deck

Craig,

It has occurred to me that you may be barking on the wrong tree.

Try the following,
Turn the BFO on and set the receiver to AGC or MGC and tune WWV at 
5 10 15 or 20 Mhz. Zero WWV against the BFO.

Switch the function to standby and back to AGC and over to CAL and back to 
AGC and MGC.

Does WWV stay zeroed against the BFO when you do this? It should.
You could have one of the oscillators shifting rather than the calibration 
oscillator shifting as you switch functions and Mega Hertz.

Same problems, poor tubes, and or poor caps, and or poor ground points.


I under stand your reluctance to pull the RF deck.

But as long as you have to go in, Be not in a rush to get out. Check and 
change any of the old caps and resistors that may be metering poorly.

Best of luck with this venture.
