Actually I find the grid current meter very useful as an indication of the
degree of loading. It's also quite easy to cause excessive grid current to flow
with a 100w exciter, and it's a good warning device.
I don't know about Lane's filament voltage, but I measured it in my SB-1000 and
it just about exactly 5.0v. My new amp will have a rheostat as you suggest,
however.
