[Amps] To short or not to short! ( filament to cathode in a 3CX1500A7?)

["Charlie" <charlie@drhabekost.com>]

Hi all-

In reviewing numerous schematics of 3CX1500A7 amps, I have noted the circuit
both ways. In addition, some appear to place a choke in the line from
transformer (or CV/ C limited SMPS) to filament  along with (/without)
bypass caps to ground.

My inclination is to NOT connect the heater to the cathode, and TO choke AND
bypass the heater wires on their way to a CV, current limited SMPS.

Thoughts?
