UTC S-19 Modulation Transformer


I have a 4000 ohm primary requirement and the specs show that 2-3-4-5 are the proper connections. The schematic calls for a center tap primary connection. Now it would seem that 2-3 are connected and 4-5 are similarly connected . Then 3 and 4 are the center tap and 2 and 5 the outer. Have I thought this through properly.javascript:void(0);

Yep. The terminal progression is P-B-B-P for Plate - B+ - B+ - Plate. So in your case, tie 3&4 together and connect to the B+ and 2 and 5 go to the plates of the mod tubes. T
