"Some 15 or 20 years ago, Border Patrol (if I remember correctly) advocated independent power supplies for each stage and (again IIRC) many who experimented with this agreed."
The driver stages for my 300b amps (left and right, just one triode each, on it's own chassis) are CCS loaded and operate from a VR tube shunt regulated, CCS feed power supply (the raw supply is tube rectified with a LCLC filter) on it's own chassis. (The DC heater supply (LCRC with one more C on the driver stage chassis) is also on that same PS chassis.
Each 300b output stage (each on their own chassis) has it's own LCLC B+ supply and it's own LCRC filament supply.
So it's a 4 chassis amp.
The driver stage and it's power supplies are also used with my stereo 6b4g amp (output stages only). So, when used, it's a 3 chassis amp.
The 6b4g amp has one LC B+ supply that splits to 2 LC filters (one for each 6b4g) and 2 LCRC filament supplies all on board.
Crazy? Yeah, probably.
