[R-390] EAC Quality

[Veenstra, Lester]

When I was on active duty and the getting the last run of receivers from
EAC, we all agreed that these new receivers were trouble. As I recall
they had a higher failure rate, burning resistors and bad small
electrolytic caps, that the previous production run receivers.

...due to the excellent design of the radio it doesn't 
make any real difference....except that the 67 EAC with all EAC modules
is 
the youngest of the pack.  I have one of those that is close.....the
audio 
deck is Collins if I remember correctly.  It's a true DOG.  It was in
the 
pile at SJC and it did not stand up to the elements as well as the
earlier 
radio's.  The plating on the chassis and modules is thin and didn't
protect 
the radio.  What a shame!

Works pretty good but will never be pretty again!  Good platform for
mods 
testing I guess.
