[R-390] R211 and HR202

Roger:

Thanks for all of your observations. 

RE: R211
I examined that resistor with a magnifying glass, it is indeed coded grey-red-orange, not grey-red-red. It looks like new, so my guess is that someone was in a hurry and did not look real close during assembly. It is not discolored at all... It measures 82K both on my DVM and my VOM. Funny how that passed inspection back in 1952......

Re: disclorated chassis from heat
In addition to the subcompartment containing HR202, the other ones are that long skinny subcompartment under all 6 back row RF transformers containing NO tubes; AND the area near tube socket V203, AND around V201's socket. This is going to be fun checking out indivdual parts in a crowded zone! Even the 5000pF discs are now dark yellow. I picked the worst looking bypass disc cap to test, and there was .001uA leakage at 250V and its capacity was bang on at 5000pF. Boy they are tough! 

Re: R390's
I have collected some R390 (not the R390A) specific msg's over the years and would be glad to post them in *Pearls*. There is so much overlap, that there are many already there. 

Thanks
