Really appreciated your posts! (both technical AND non-technical)
"The acid in the orange juice will damage the substrate causing the harmonic
distortion at audio frequencies to be much greater so no it would not be the
equivalent of an Orange Drop.
But...if you dip them first in the juice from the Kielbasa used for theballast
tube replacement this will be prevented....also the oils from the
Kielbasa will actually smooth out the harmonics and then it will function
more like an Orange Drop...

(from 2011: my goodness, I searched my R390 Group emails for "kielbasa" and
the search went back 15 years!!)
Going to miss you! Take good care and God bless!!

It’s been a lot of years, many friends have come and gone.
It’s funny how fast life passes.
These receivers transcend time. They are worth the effort. At some point we
wear out before these radios do. Ive divested myself of all of mine except one
original R-390/URR and enough spares to keep it running. What a great radio.
The non-cost reduced original and strangely the cheaper version.
I wish you all the best and hope the new guys coming aboard will carry the
flame. Respect them for what they are. There are still a lot of parts
available…for both versions. Don’t try to make them what they weren’t meant to
be.
I can’t do the work anymore….Parkinson's has taken that from me. So I bow out
and leave that to those who still can!.
Don’t forget the dead horses, the black goo from the original filter caps, the
special sausage used to make these radios run and the guys from New York to
California that shared their insight and humor!
