[R-390] Both R-390A's Play!

[Philip B Atchley]

Hello all.
More info on those two R-390A's that followed me home yesterday.  I
plugged a temporary diode into one of the rectifier sockets and slowly
brought the variac up to about 60 Volts and let the caps get used to
that.  I then plugged the rectifiers back in and finished bringing it on
up to rated Voltage.  I didn't spend much time forming em as they are all
going to be replaced by below chassis filters anyway.  

I then connected speaker and 'antenna' (6 foot wire) to each receiver in
turn.  BOTH sets played on all bands as evidenced by the calibrator and
lots of stations.

NOTE 1:  These are the two "cleanest" R-390A's that have ever crossed my
bench 8^)!  The last three consisted of a Collins followed by two
Motorola units.  They were all very grimy before I started work, in fact
the last Motorola unit had "burnt" behind the front panel and had to have
the terminal board replaced and some wires repaired.  These both are
"quite clean", harnesses look new, in fact below decks look like they
just came out of the EAC plant.  Naturally topside is a little dirtier
(mostly dust etc).  Both gear trains are the cleanest I've seen come in,
though BOTH will receive a thorough solvent cleaning to remove any
hardened grease.         
 
NOTE 2:  The unit I have chosen to keep for myself has the following SN's
bottomside (all EAC).  The topside modules all have EAC inspection stamps
(can't see S/N labels yet) so I suspect it is an all EAC unit. I'll know
more once I dig into the topside.  I'm doing bottomside work first.
