Due to recently incurred medical expenses I am forced to sell the R-390A
that I acquired a couple of months ago.
I have turned the receiver on and it is evident that it is in need of
work. Mechanically the receiver is in good condition but obviously needs
to have the band-change mechanism cleaned and lubricated and some of the
controls, like the zero adjust and antenna trim, need to be repaired.
Electrically it is readily apparent that the receiver needs a thorough
alignment since the only signals I can hear are a few AM BC stations on
my 40-meter 1/4-wave vertical. It does appear that all filters are
functioning since I can hear the narrowing of the IF bandwidth when
switching from 16 to 8 to 4 and down to 0.1kHz BW. The BFO works but the
alignment is far enough off so that rotating the BFO pitch control does
not sound normal. The line level and carrier level meters appear to be
original and are both functioning. Other control functions (line gain,
AGC, limiter, audio repsonse and break-in) appear to be working.
Unfortunately I have no access to even a tube tester and signal
generator so cannot do even the most minimal work on the receiver.
I hope that the above descriptions are not too confused but I have never
owned an R-390A before and have only learned a bit about the receiver
from reading the posts to this reflector. I do know, based on an answer
to one inquiry I made, that this receiver does have an R-390A IF strip.
If anyone on the reflector may be interested in this R-390A I will be
glad to provide any additional information required and will be able to
provide .jpg images either tomorrow or Saturday. I will try to provide
whatever digital photos of the reciever that anyone would desire plus
would answer any questions as thoroughly as possible.
Thanks,
Jack, AE7DX
