[Amps] Alpha 77Dx -Adding Grounded Grid Filament Choke

[Paul Christensen]

Last week's discussion of GG filament chokes got me thinking about modifying
my Alpha 77Dx which I believe, ties one side of the filament to the cathode.
I would like to cut this tie and user a R.F. Parts Co. FILRFC-30 filament
choke.

I am assuming that a combination of HV-rated 0.01 uF and 0.1 uF disc caps
could be used to bypass each side of the filament tube terminals to ground.
Anything else I should consider before doing this?  Thanks!
