Miniature Tube Amp

The following is a work in progress. This is based on the Powerman by Mark Lavelle, but I have markedly changed the voltages and resistor values. The resistor values are based off the Sylvania data sheets, at 100V B+. This amp won't have much head room!

Other changes:

Used a transformer that has a lower filament current, so no voltage dropping resistors should be needed.
