Looking for a 5V/30A filament transformer with a 240 VAC primary. Hammond and Stancor types are available but only with a 120V primary. Finally getting around to converting a 77Dx to a 3CX1500D7 for instant-on capability - and hence the need for the higher secondary current. Thought I would check here first before contacting Dahl. Tnx! Paul, W9AC
