R14 470k change to one watt or use 2 one half watt 1megs this is something I do with every radio using a 35C5 or 50C5. Consider adding a 50ohm to the filament string something I do most of the time. C31D 22uf 50 volt to 250 volt most of the time use 250 just what I have on hand most of the time. 12BE6 try different ones will make a difference on Band 4 forget the tube tester on this one. Simple long wire ant. 10-15 feet. David

What wattage rating should I use for that additional 50 ohm resistor on the filament string?

It's not how bad you mess up, it's how well you can recover.
