[R-390] Purple Power and Proud Owner

[Forrest Myers]

Hello All,
 I've gone through the R-390A/URR I bought from Don Reaves last Sunday and
have learned a lot. The receiver is basically very sound. I have decided not
to power it up again until I replace a couple of capacitors in it and am now
doing some checking and cleaning.
 The name plate was missing and the number 557 was written where the name
plate belonged. All the modules I've check are made by Capehart and have an
order number of 21582-PC-61 . This includes the IF, AF, Crystal Osc, and
Power modules. The PTO and BFO are both made by Progressitron. The two diode
tubes are still in the power module. The ballast tube is in place. There is
no diode load jack.

From the above information, I've decided the unit was built by Capehart but
have no idea as to when.

I built a 600 ohm speaker yesterday out of an old speaker from a Ford pickup
and some scrap plywood. Used a transformer supplied by Don Reaves. I sanded
the speaker box to where it was almost smooth and applied lots of gray
paint. Doesn't look bad at all. The price was right too.

Today, I decided to clean up the top and bottom covers. Found some stuff
called "Purple Power" on the shelf and gave it a try. Really amazing stuff.
It cleaned the covers almost instantly with no scrubbing at all. Took off
all the dirt and various other marks without a problem. Purple Power is made
for removing road tar from cars but does a great job on R 390A covers. Don't
know if it will work on Non-A covers or not.
