Predicta Picture Tube Replacement
Hi everyone

I was wondering what modifications would be necessary to use a replacement 21FDP4 picture tube in a Holiday G4242 Predicta set. This would be a replacement for the original 21EAP4. I read somewhere that the filament voltage was higher on the replacement tube. Did Philco provide instructions to update/upgrade?

Thanks for any help anyone can provide.
