Hello, Has anyone done the solid state replacement Vib with the AF67-68 mobile or universal supply? Might be similiar. I have several Mil gear Vib transformers that appear, by the schematic, to use 1/2 of a 12V heater vinding with the other 1/2 supplying the tube filaments. It is a dual mode tranny with 110 AC winding as well. Bill, KB3DKS/1
