Thanks to all who have welcomed me and have passed on tips, recommendations, and sources of information about my R390A.
I purchased it last week at a hamfest; very dirty but physically looked to be complete. The owner said "it worked the last time
I turned it on".  Brought it home and powered it up- straight off 120VAC (no variac).  Had to use earphones cause no 600 to
8/4 ohm transformer (its on order).  
I was lucky.  The calibrator worked on 28, 7, and .7 MC bands. Could barely hear a strong BCB station, and copied some SSB
on 40M.  Selectivity 'worked' on all positions. BTW the calibrator was good signal strength. BFO 'worked'. I could see that a
bulb was out, and no indication on Audio Meter. Fiddled with other knobs and switches and they apparently are 'good'. Turned
it off and put it back on the shelf until my present project is finished (Hammarlund SP600).
Might take me a few weeks to finish up my project, so in the meantime I will gather more info and parts for updating it.  The
cosmetics of the front panel are very good, but dirty. The knobs will need re-paint.  The Carrier Meter works but is very opaque
and smeared glass, on the inside of it. Any ideas how to clean it on the inside?
It is very reassuring to have a source to go to when a question or need arises during this restoration.  Thanks again.
