Default High voltage step-down switching regulator

Hi,

for my forth-coming bass amplifier head project I'm considering a high voltage switching regulator for obtaining the 250...300 V @ 0.1 A screen supply out of the raw 420...450 DC voltage. Any ideas or applications available?

Best regards!

why? - unless you simply don't have enough I from the HV supply, need ~30% extra current

you're likely burning more power in heaters

Because I'd see it as a challenge! Not any tube bass head features a switched step-down regulator.

But you'd prefer something like a Maida?

Best regards!
