[R-390] S&W R-390A, Update...

[Steve Kent]

After a long wait, I've finally gathered up all the parts that I need to 
at least get close to plugging this beast in.

Earlier I replaced the missing 455kc crystal in the IF deck.  Why was it 
was missing? Who knows. This week, I finished rebuilding the 30 and 45 
uf multi-gang caps and testing the mechanical filters which thankfully 
seem to be ok. Last night I installed my new L505 choke, R508 2.2K, C511 
5000pf, C553 0.01uf and replaced the notorious leaky corroded 8uf in the 
audio section with a 10uf @ 35v Sprague axial. Pulled the PS section to 
give it a look over and guess what? I found CR801 & CR802 underneath 
V801 & V802! So I pulled V801 & V802 out and set them aside. Diodes 
checked good. Seems like someone saw empty tube sockets and stabbed two 
tubes in. It looks like the socket bases were bent and then un-bent. I 
also replaced some missing tube shields throughout the receiver.

Tonight, I will replace the three broken tuning slugs; hopefully I can 
get the two old ones out easily, one is missing. More importantly, I 
will check and double check all of my work done in the IF section.

I am getting pretty close to bringing this thing up on the variac.... 
Maybe tonight?
