I have built a version of the Legacy 300b amplifier (coutesy of Thorsten Loesch) using a conventional power supply using miletary surplus transformers and chokes (oil filled c-core), Cap 10mF - 15H choke - 200mF cap. I have used cheap Audi Note Trans 144 (the experimenters version.It works very well and is essentially quite detailed and musical albiet soft on the bass with a slight electronic haze? - probably due to the regulated filament supply - the schematic for which comes sraight out of the AN Conquest.
So a bit of a mix and match amp really.
Has anyone tried using a constant current source as a load to the C3M instead of the resistor?
My fear is that it is 420 volts and I know that the CCS cannot withstand this - so would need some kind of protection.
