Oscilator coil for Cathedral 60
#2

If it's the outside winding- the tickler winding, it's fairly easy to rewind. It is NOT a critical winding. I use #34 wire since I have a spool of it; any wire #34 to 38 will work; as I recall it takes about 17 turns and they can be wound without removing the coil if you are careful. The exact number of turns is NOT critical. Several people here will be upset with this advice but I have done this perhaps 5 times.

The wire usually opens on the outside where it makes a 90 degree bend to the solder joint. (The original coil winding machine created a stress at this point which opens over time). It is possible to carefully unwind one turn (or two) to find the open and reconnect it.

If you rewind or find your open winding, you will need to carefully scrape the insulation from the wire with a small, sharp knife blade before soldering.
