> front panel that looked like new and a back panel that featured
> an original line cord with metal 3-wire plug neatly stowed in its
> clip. I popped the top cover and my jaw dropped. Aside from a

> Long story short - all the tubes were either GE or RCA (except
> for the ballast, of course) and bore the same "68" date codes as
> the original font panel meters. Even more remarkable was that
> aside from the 0A2 and 26Z5's (which run hotter) all the silk
> screen markings on the tubes remained fast even when rubbed with
> a damp cloth. This was a new radio! The only sign of age was a
> hardening of the insulation in the line cord and slight yellowing
> of the white lines on the knobs. A close inspection of the
> "green" screws revealed no scratches and the tubes almost seemed
> welded in their sockets for not having been touched in 40 years.
> As expected, they all tested as new in my TV-7D/U.

> All the radio required was a good cleaning with compressed air
> and a dry paint brush and some soapy water on a cloth. Some
> Tarn-X was applied to the silver plated surfaces with Q-tips and
> a few of the knobs had some small paint chips to touch up.
> Electrically, the radio came right up to spec with the exception
> of transformer Z216 in the high-IF which failed to peak and was
> replaced.

> Since most of us will never get to see what a new R-390A looks
> like, I took photos of all the modules before reassembly and posted
> them at my Web site. Thirty high-resolution photos tell the story
> at www.wa3key.com/r390a (r390a-01.jpg thru r-390a-30.jpg)
>
> I e-mailed the seller informing it was the cleanest R-390A I've
> ever seen and inquiring as to the radio's origin, but he never
> replied.
>
> Enjoy the photos...
