Ron;
I think that the Hammond 270EX would be even better, the 5 volt winding is 3 amps and the 6.3 volt is 4 amps, the H.V winding is 144 ma. The question is, will it fit? The other may work but I don't know how close to 2 amps the 5 volt winding actually is since a 5Y3/5Y4/80 runs at a heater current of 2 amps, I would assume that 2 amps is the working current and not the max, the 6.3 volt winding is good enough on all transformers mentioned since all are rated for twice what the tube filaments draw, which is 1.55 amps.

Arran
