[R-390] OT: Low-voltage tubes

[Scott, Barry (Clyde B)]

At first I thought this one was going to be a real dog but after a closer
examination, I think it will clean up very nicely.  I may have to recover it
as the original fabric is very dirty and doesn't want to come very clean.
Also, the adhesive is wanting to let go in places so it may just have to be
done.  Otherwise, it seems in good shape for its age.

It should be a fun little diversion.

Thanks again,

Fun little radios, a lot of the guys (any girls?) on the list have them. 
Incredibly good sound and sensitivity when they're working right. Tubes 
don't glow like most others due to the low voltage. You'll enjoy it a 
lot. Try to find some spare 1L6s, though. Although not really rare, most 
of the NOS JAN surplus was bought up by a few dealers who now charge 
'RARE' prices, mainly due to the interest in TOs over the last decade 
(IMHO). Like anything else, it depends how good you are at digging 
around and how impatient you are.

Tip: Look for junkers at hamfests, flea markets, yard sales. You can get 
a complete unit pretty cheap, usually with the 1L6 included. I've found 
one at a yard sale, one at an antique shop, and a chassis with all tubes 
(and an R-390 S-meter) in a box of 'stuff'. Got my H-500 back in 1980 
(before they became 'sought') for $10, love it!
