[R-390] The second 390A

[dog]

I've been using a Fluke 189 or an old HP427A FETVM, both 10MΩ or more 
input. I'll have to do some further inspections and also get the SA/sig 
gen going. A bit of signal tracing back from the IF input should be easy 
enough to do. Not sure how much I'll get done today, but maybe I can get 
the first one looked at about the high voltage on E209 also.

The power cord was so old on #2 the innards were so brittle it just fell 
apart. Luckily I found it right away. I'd like to find that mod for the 
new AC filter input.

This was the first trial in a long time of the PS on #2, it originally 
had the diodes installed and the tube sockets crimped shut. I replaced 
the sockets, re-wired everything and someone sent me a couple new 
rectifier tubes. It fired up just fine. The radio had been sitting 
around for maybe 20 years here and I was swapping modules out of it with 
#1 to get all the mods done I wanted. Mostly just the pertinent black 
beauties and coupling caps plus re-capping the audio/PS sections with 
filter caps under the deck. Also on #2 I had to rebuild all the 
mechanical filters. That took a year or more.

I've been thinking about re-painting the front panel on #2, it's got 
some holes drilled in it for the DB meter adjust that I removed. Looks 
like I may need a few small knobs too, like the ant trim. But get it 
working first, I kinda remember it worked to some degree 20 years ago 
when I got it. I think I gave maybe $50-80 for it at one of the local 
hamfests. I had 3 of them but loaned one out (the best one) and never 
got it back. I don't think I ever gave more than $80 for any of them. 
Why I needed 3 is beyond anyone's imagination?
