Well, I have not looked at it yet. Honestly, this specific RCA is not my bucket list radio, so if too many things are open, I might just give up on it, as the expense will be to great.
And I cannot find the inductances of both chokes: they are both listed in Ohms, 3,000 Ohm each. i of course could possibly try to get to the wire and measure it on my LCR meter but this is only if the wire is intact. Another thing to try - counting turns. I hate it.
The antenna coil has flat disk type winding. Grrrr.....
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
