This is a question for the super-members(with more experience than me!). I went back to Ron's instructions on neutralizing a neutradyne(511) radio. I have made up adapters for both four-pin (26s) and five-pin (27s).
But wouldn't a 26 or 27 with a blown filament do as well? This is simply academic, as I do just as Ron says to do, with the tube that will be used in the circuit.
I've already done My Freshman AC 31, and it sounds pretty good. But then it should, because it has an electrodynamic speaker. Only neutradyne
I've seen that doesn't have a "cone" speaker.
At any rate, it's EASY to find a 26 with a blown filament. I wouldn't cut a filament pin off even under a death sentence!!
