Do you know the required inductivity of this coil? This would make it easier to find a replacement.

From article by R.A.Moog "A TRANSISTORIZED THEREMIN"I found out that this is (Moog 11-311)75 Mhy machine-wound coil by a special method called progressive-universal and cannot be duplicated by hand-winding.In fact there is a chance to replace it with three ferrite-core r.f.chokes.Of course orginal part would be best....

You can use 3 of the Bourns (JW Miller)6308-RC in series.
in stock here

These are 25,000uH each (+/-5%), so in series they total the 75,000uH required for the pitch circuit. They are 3-pi universal wound. Bob suggested them as the replacement for the progressive universal wound 75,000uH coil.

Bob also suggested the Meissner 19-1053, but I don't think they are still manufacturing.
