Sounds really interesting. What did you do for the 5V 250mA filaments?
Then I was using current-regulated DC. Basically the Ronan Reg with whatever number of stages were required to deliver 5VDC at the required current. I *think* I started with a 10V 1A filament tranny. Filaments were dead quiet.
Today I would scrap the SS regulators in favor of filament chokes with a cap input only if I needed it to get the required voltage. Make sure the choke is the last element before the filaments. I want to stress that I'd make that change not because I think current regulated filaments are "bad", but because my design philosophy has shifted toward simplicity and as few active components as necessary. But that's just me.
