Get yourself a copy of either an GE tube manual from the 60s (post 1962 - the 1962 manual doesn't have it - they have FM multiplex adapters in the sample circuits in the back.

GE's 1964 manual has one with a 6GH8 as the tube, and uses common Miller 19KHz, 67KHz, and 38KHz coils. I'd scan it, but the manual is still under copyright.

You can tap filament and B+ voltage from your existing unit. This was popular in the 1960s - and there are even project plans in Radio Electronics and Popular Electronics magazine, available at American Radio History....
