Yup. Tube, chassis, shields, etc, ad nauseam. Normally see a bit of 
reactance caused by the parasitic (I love that word) reactances present in 
the "dummy" resistor clipped across the anode, but in this particular case, 
I see *way* more than usual. Would be nice to put numbers on the *way* more 
part, but that's not gonna happen any time soon.

Speculate away gents!
