[sdiy] B+ Current consumption

[Travis Shire]

Don't forget about your plate load resistors. They'll drop the voltage
that's actually seen by the plate. Dunno what volatage you want to see at
the plate, but I'd think the 300vct would be a better bet. 12a*7 tubes sound
better at higher plate V. The highs are nicer and there's none of that
artificial tonality that they take on in a starved plate design.

What's the application anyway?
