Guess they were not as unobtainable as I thought!  Thanks for your help.
Got two of the ovens on order from Barry Hauser ($25 min, you know).
As for the 17 MHz replacement, typical Engineer knee-jerk.  Not on the
shelf? Start whipping up a replacement from the parts drawer!  Since my
R-390A is an old Collins, 1955 contract, I am very hesitant about doing
mods.  Even thinking about restoring the 26Z5W's.
Speaking of mods, anybody have a spare IF Deck floating around (R-390 or
R-390A)?  Want to mod it for 1,2,3,6,16 khz bandwidth and Lankford SSB
detector.  How about adding SMA connectors to the RF Deck so that you can
bring out the LO.'s for electronic readout?  When am I going to get around
to doing the Cap replacements?  Anybody out there have an R-725 and an
electronics bent?  Need some info on it.
And where do you go to brag about your new acquision?
