Members,
We are having trouble getting a message through from Norm, and I'm
reposting it to see if I can detect a problem.
So, this is Norm's radio, not mine!

Original message:


Thank you to all who responded to my post last week about R-390 module
compatibility, with special thanks to Don - WC4N, who solved the
mystery of my incompatible power supplies.

Many on this list will recall when I posted photos of an exceptionally
clean, all original, 1968 EAC R-390A in November 2008.  Those photos
are still on-line at   http://www.wa3key.com/r390a

This time I've posted photos of an R-390 Non-A that I just completed
this past weekend.  It was listed on eBay as "old" and "as-is" but
looked promising, so I took a chance.  What greeted me when I opened
the box exceeded all expectation... an all original R390 in reasonable
working order with no signs of heavy use.

Photos are posted at  http://www.wa3key.com/r390  if you'd like to see
what an exceptionally clean, all original (except for the meters) 1955
Motorola R-390 looks like.  It came with meters, but they didn't match
and with radium paint that was severely discolored.  Photos 01-31 are
of the frame and modules while 32-42 are of the assembled receiver.

The only parts needed to restore this beauty were; bridge rectifier
CR-801 in the power supply, a new fuse holder for the B+, and
transformer Z206 from a parts RF deck.  The paint is original (even
the odometer cover), but unlike the '68 EAC, knobs refinished by
Howard - W3HM were installed.

Performance is phenomenal.  I have restored eight R-390A's and none
equal the sensitivity of this radio.

Enjoy the photos.
