[R-390] R-390 <> R-390A IF decks?

[Dan Merz]

Gary,  I used Tom's instructions for putting the 390 IF deck in my 390a.  It
worked well and is still in my receiver.  I wouldn't classify it as a casual
job because of the tight quarters for moving connections around on the
bottom side of the chassis,  mostly to get the filament circuitry rewired.
The instructions were very clear about what to do and I was happy with the
result.  Good look on getting the R-390 deck - it took me a year or more to
find one.  I would add that the greatest improvement I made to the 390a was
modifying an audio deck and putting that in.  I used the 6360 tube mod;
there are others including a later one by Mike Murphy written up also in
Electric Radio June 2004.  If you are interested in more details, contact
me.  There are easier ways to achieve good audio just by connecting an
external amp to the diode load terminals at the rear but I succumbed to
having a mod inside the radio on a spare audio deck. Dan.

Hi R-390,

Please reply to the R-390 list on this one, since it may be of general
interest. If you want to reach me directly, please
use   user3 a at t uwave  dot com , since my "r390a" address has
been compromised.


I _may_ have the opportunity to obtain an R-390 IF deck.
I'm wondering if it is a "drop in" to an R-390A? 
What (any?) changes are needed, other than possibly tubes and fil wiring?
Is this a "good thing to do"? While I love the steep skirts of the 390A IF
deck's filters, I've heard Very Good Things about the R-390 IF deck's L-C
sound. 

Thanks for any help/info/insights.

Regards,
Gary
