Hendershatalways used Ll red and L2 yellow for easy identification. L4 is made from No.18 gauge copper enamel coated or Formvar magnetwire. 14 turns close wound over the outside diameter of L3 inthe center of L3 Plastic electrical tape is wrapped around L3to form a smooth surface for winding, after winding the 14 turns.wrap additional tape to hold L4 in place. The handwrapped capacitors are the most difficult to build andare the critical key item to success or failure in producing results. The foil from two capacitors, Pyramid electrolytic TM 58, mustbe removed from the can that encloses the foil by cutting thetop or bottom off with a hack saw or other cutting device.
Thecoiled foil is removed from two capacitors and spread out on aflat table.
Wipe off excess electrolyticsolution so that it is dry. One side of the paper holding thefoil will be full length, the opposite side will be split withterminal connections appearing at each end of the split portion. You may use a substitutecapacitor and trim foil to size. Prepare two cylinders of metal with dimensions of 5 in. A stainless steel sheet metal .032 thick wasused in Hendershot's cylinders, open at both ends.
