[R-390] critical location for triple mica tubes

[Scott Bauer]

 I have just aquired a pretty sad R-390A at a hamfest
last weekend. I also picked up some 5814A's with
triple mica spacers. How lucky can one man be :-)
 I wonder if there is any particular
module in the R390A that would benifit from the triple
mica 5814A?  I am guessing the manual would have 
called for such a tube if it was critical.

 I will probably use the radio for parts but I am still
interested in any opinions.

 I am just happy to get the needed meters and filters.
I have never seen a radio in this condition. It must have
been on the top of the pallet of blue stripers. Or possibly 
the bottom and all the crap from the others flowed down
 into it :-) Still worth $75.00 though! I should have taken
pictures.
