You'd either have to ask PJ, or you'd have to buy one and try it out. It's still not the most optimal solution, as it puts out a regulated 6.3V, which we drop with a couple of low value resistors to get to 5V.
EricS said:... insert a 0R1 resistor in series that will bleed off 0v19 and shift the heater range down to 4.97v to 5.19v?
Yeah, you would be pulling the winding down a little bit, and the paralleled resistor would pull the voltage down less with lower line voltages and more with higher line voltages.EricS said:Paul: I presume you are recommending the resistor in parallel to place a more "even" load on the AC filament? Does it achieve the same result if I put a smaller resistor in series with each side of the filament?
Hmm, so bring the 5V AC current right up to 2A (with a 50 ohm resistor in parallel with the filament) and call it good?Paul Joppa said:Actually, the primary is designed for a nominal 117 volts 60Hz input and the 5v winding is specified at 2.0 amps RMS.
