I picked up a small tombstone Delco radio at the last WARCI meet earlier this month rather inexpensively. It's a 1935 model R3202:

I picked it up mainly because I have an extra power supply (thanks to Terry ; see thread http://philcoradio.com/phorum/showthread.php?tid=15152 ) that steps down 120VAC to the proper 32 VDC to operate the radio.
The problem I've encountered is an open primary on the detector coil. Number 6 on the schematic. It is not a straight forward coil with two distinct windings, but rather has a wire running up through the tube, out a hole in the side, around a couple of turns, back through the hole, down to the other end. In other words, it would be very difficult (for me anyhow) to rewind properly. The secondary measures 11 ohms, but I have no idea what the primary should be.
Is there such a thing as a universal replacement detector coil, like AES offers for the OSC and ANT coils?
