[R-390] My First Boat Anchor...

[Mark VandeWettering]

Howdy all.

I've just acquired my first true boat anchor: a Collins R-390A bearing
the Motorola serial number 519, and by the order number on the back,
appears to have been manfuctured in 1956.  I acquired from my boss as
he's retiring and downsizing.   It appears to be in very good
condition: front panel is immaculate.  The inside is a bit dusty and
grimy, but all the mechanicals seem good upon inspection.  A couple of
things worry me about the radio though: the power cord seems very
light weight, and is a two prong connector.  My primary concern above
everything is to make sure that it is safe to operate.   Beyond that,
I've got very little experience in cleaning and maintenance of this
kind of vintage equipment.

Can anyone recommend some resources?   Initially, I'm looking for a
"best practices" modifications to improve the electrical safety, but
beyond that, I'd like to to get some guidance on how to proceed to
clean and tune this radio.  Any links/information helpful to the
beginning boat anchor enthusiast would be helpful.   Anybody in the SF
Bay Area who might be willing to act as an Elmer would be even more
helpful.   I've never tackled a project quite like this before, and
I'd like to benefit from the experience of those who do it right.

Thanks gentlemen!
