[Amps] low output with QRO amp - SUCCESS-

[Steve Bookout]

Hello all,

Put two spares in the amp chassis, defeated the HV and let it 'cook' for 
48 hours.
Hooked the HV up and let it cook a while longer while I shoveled the new 
batch of snow.

Tuned it up by the book and was getting 1300 watts out with about 30 
watts drive.
All voltages and currents look fine.

So, it appears the low output was due to the dud tube with the open 
filament.

Thanks to all for the suggestions.

I think I will take my Dremel tool, with the rotary diamond disk, to the 
dud just to see what it looks like inside.
