Hi

What are you using the Rb for?

A switcher is going to put even more hash on an already dirty 10 MHz output
on the Rb. That may or may not be an issue to you.

So a cheap switcher down to 18-20v and a pair of linear regulators to get
the 5 and 15v? I was hoping for something more off-the-shelf; my T-bolt is
running off the power supply in the TAPR/tvb group buy from a few years ago.
