[ARC5] running ARC-5 receiever fillaments on AC.

[J Mcvey]

Thanks, The reason I ask is that I an old home-brew receiver power supply that someone made.
Now the next thing i discovered is that the transformer is probably under -powered.It's a stancor PS-8416 125-0-125 @ 25ma. 
The rectified voltage may be sufficient but the current is probably too light?

What is the consensus on ac vs dc filament supplies for the receivers?
Does it make a difference? Do they tend to get hum in output?
-----------------------

It has been my experience that AC filaments inevitably introduce some amount of hum, for various reasons.  YMMV, of course.
