Ordered a new volume control to replace the bad one.

I have a question, if I replace the 117Z3 rectifier tubes (2) with a 1N4007 diode & resistor, will I have to strap pin 3&4 the heater pins. It looks to this may not be necessary because they are not in the series with the other tube heaters?

What do you think?
