[R-390] R-390 restoration

[DAVID MEDLEY]

I have followed with interest the thread re solid stating an R-390 and he=
artily concur with those who oppose this idea. I have spent the last seve=
ral years restoring R-390 radios to as near original as I can but this jo=
b is getting more difficult as time goes by. This is due to the dwindling=
 supply of spare parts, especially tubes. The 3TF7 seems to have joined t=
he list of unobtainables together with the 26Z5W and the 6082. There are =
a number of solutions to replacing the 3TF7 and solid stateing the power =
supply is no big deal. The 6082 is another matter end  I would love to se=
e a thread develop towards replacing them with something readily availabl=
e. I think there have been thoughts given to solid stateing the VR circui=
try but that would be a major departure from the original and spoil the r=
adio as an item I believe. Other small parts such as antenna relays and R=
F coils can oly be found in junkers and parts radios and I am always on t=
he lookout for those.
