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

[Glen Zook]

I use AC on the heaters in my BC-453, BC-454, and BC-455 receiver with no "hum", that I can notice, in the audio.

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.
