Has anyone used a Maida-ish design to regulate B+ for a tube mic's power supply?
I want to be able to order a batch of PCBs and then transformers from a single source and be able to use them on any tube mic project. I played with some different B+ voltages and loads (100VDC - 220VDC) with passive filtering and with a Maida regulator. The Maida adds some parts cost, but it's easy to get 100 to 220 from the same transformer.
In other words, I could buy multiple transformers like this one, without knowing what project requirements would be:

Same transformer and same PCB for multiple different projects with a few different components.
Started thinking of this after reading the @rock soderstrom thread with an already quite versatile PSU design:

Passive (for B+, regulate heater) might be the smartest way to go, but I do like the idea of using the same transformer for all future projects.
