[R-390] Non-A alignment question

[Paul Staupe]

I recently got a R-390/URR (non-A) that was working properly when it was put
in storage about 20 years ago.  When I received it, there was audio hiss,
but no stations received.  I tried tuning it up using the manual with my
URM-25D and a VTVM on the diode load to no avail.  I finally gave up and
tried to peak a 1500 kc signal directly to the unbalanced input.  What I got
was a band of BCB stations that was received about 630 kc higher than
indicated on the Veeder Root counter... eg. WHO, Des Moines at 1040 would be
received at 1670 kc, WLOL on 1330 would be at 1975 etc...

Does anybody have any suggestions as to what this could be?

Thanks,
