I may never do a post power amp based on a pair 300b , using Surface as a pre-amp , as what was on my mind when I first captured the CM concept.
I may, however, do a post power amp, based on a pair of 6L6 , which would not require a CM filament power supply.
Surface does not use the CM DC power filter, nor would a super-scaling 6L6 post power amp.
I am sure this answer may not be taken in the correct way, so I leave it at that....... ... . . . . .. ... ... ....
