Having to pull the RF Deck to clean the bandchange switch wafers (a chore that I seem to have to do every two tyears or so) reminded me of the need to re download the Y2K manual http://www.hausernet.com/r390a/ . This is not the original technical manual mentioned in previous posts.
Thanks to the authors for putting this together. Apologies to forum members who may have this revised manual with some colour pictures, but it may be of interest to new owners.

R-725 is a direction-finding set with an IF strip similar to the R-390, developed by Motorola and built by Servo and Arvin. No more than 300 sets produced.
R-1274/GRC-129 model is a special variant, widely in use by the NASA for the APOLLO effort.
For further information see Fred Osterman: Shortwave-Receivers - past and present.
