re: tuned filter power supply

Is the target 'trap' frequency actually 120 Hz or 
slightly above it?

The cathode (-) power supply may have a large steel canned capacitor 
around 1 uF. It is rated for high AC voltage in doubler service, and 
is usually polypropylene dielectric. If it is rated for few kV, it 
makes a very nice capacitor for tuned filter power supplies, across 
the appropiate choke to make a 120 Hz parallel 'trap'.
