[Boatanchors] VR Tube Subs

[Al Klase]

Bob,

I'd expect you can get away with that. However, substituting the 0C3 
105-volt regulator for the 0D3 150-volt regulator is going to increase 
the voltage drop across the series limiting resistor, thus increasing 
it's power dissipation. Assuming 30 mA current, that's pretty typical, 
it amounts to .03 A x 45 V = 1.5 watts. Probably not a big deal, but pay 
attention to how hot the resistor gets.
