As luck would have it it seems to be the same gauge that Peavy uses in their giutar pickup coils. I think I can get a small amount from a friend in the shop. You are correct they use #42. The other saving grace is that it is a magnet and not as pickey as an rf choke. There is some adjustment in the position of the magnets so I if I am not dead on I will have some adjustment. I am looking at the bobbin winder on a 42 singer sewing machine. There is an external winder that I may be able to adapt. If That doesn't work I intend to hand turn it the larger coil has 1162 wraps and I am a very patient man. I have wound chokes for the bias supply in a uhf television transmitter before but that was #14. I will keep y'all posted. The main problem I see is not breaking the wire in the process. If that happens I'll spend the $50 for a new gauge. It is worth a shot.
Thanks for your help.
