The issue with the #45s is that they require more B+ voltage, and more bias I believe, I think you can use the same output transformer. It may be pretty close anyhow, the #45s run ar 2.5 volts but draw 1.5 amps, the 71As run at 5 volts but draw .25 amps, so the same winding with 1/6 the current draw. Are you sure that the original transformer has failed? Does it run hot, or smokes, or is open circuit?
Regards
Arran
