[R-390] Solid State Mods

I'll fix it for you Phil! Send it as-is and I'll make it as good or better
(probably much better) than the original modifier! Documented, with
performance specs...

Subject: [R-390] Solid State Mods

Ahem!  Contrary to expressed opinions (not just you, Phil) there is NO
prohibition on this list regarding modifications to the R-390.  Some folks
don't LIKE the mods, and express their opinions, but if its on topic and
isn't just to stir pots, then its quite reasonable fodder for thought and
discussion.  I think the general consensus is that a full solid state mod of
all the tube circuits in the R-390 would be a major undertaking with no
guarantee of results.

I have an R-388 that was almost fully solid stated, and it quit working
before I had a chance to analyze how well (or badly) it performed next to an
original one.   I have no documentation on the mods, and there are lots of
'loose ends' in the receiver.  With too much ripped out to ever put it back
together (the R-388 is not modular like the R-390 series), a kluged on
Collins mechanical filter adaptor that sticks up over the top panel, and
several homebrew printed circuit boards it is quite a sight.  It is
certainly an example of how a project can go awry.
