There's a quickie way to verify whether (or not) the fly is putting out. Remove the 1X2 and using a well insulated screwdriver, bring the metal tip of the screwdriver close to the plate cap connector. You should be able to draw a hefty RF 'air arc' a quarter to half-inch long onto the screwdriver. If you get the arc, that tells you everything 'upstream' is working.
I was thinking maybe a hard-leakage path from the 1X2 filament winding to ground mighta developed, based on your earlier statement of hearing a sizzling noise. Just for the heck of it (with the set off), using the highest ohms scale on your meter, measure from ground to the 1X2 filament winding. It should read infinity (open circuit). If it reads anything at all, it would indicate an insulation breakdown that's lugging down the HV.
