Hi all,
Picked up a FRG-7 as part of an auction lot, and it's in need of a pretty heavy restoration - both cosmetically and circuit operation wise.
First up will be electrolytic cap replacement and a thorough check that all supply voltages are where they're supposed to be, and I'll go from there to see what other work needs doing.
But I also notice that the previous owner has pulled most of the components associated with the BFO, including Q408 & T406.

Looks like Q408, a 2SK19-GR, can be replaced with a common N-ch JFET like the MPF102 (being in Australia, NTE equivalents are not common here) - hope someone might be able to confirm the MPF102 is suitable?
And for T406 - guess I'll just try any donor variable inductor coil, especially if it comes from a 455kHz section of a suitable donor radio, perhaps may need to alter the value of C437 to bring it to proper resonance?? Unless someone has a suggestion for a specific, readily available equivalent?

Thanks in advance,
Jason
