[ARC5] Simple Question Arc-5 receiver power supply requirements?

[J. Forster]

Previously, it was posted of the 60 mA of the dyno rating, 10 mA was for
accessories. That leaves 50 mA @ 250 VDC, or 12.5 Watts.

So, the nominal power consumption is:

Fils:  24V @ 0.45 A   = 10.8 Watts
B+:   250V @ 0.050 A  = 12.5 Watts

I'd like some actual numbers.

Thanks,

-John
