Hi all,
Has anyone ever explored or heard of someone exploring the idea of isolating, rectifying, and smoothing at mains voltage with a much higher capacitance to get a cleaner DC, and then boost converting from 170 VDC to B+ voltages for plate supplies? I ask because 200V capacitors are cheaper than 450V capacitors in much higher values, and PTs are the most expensive single part in most tube amplifiers.
This is just food for thought for now, to see if this is even a feasible idea.
Thanks in advance!
Dave
