Muntz And The Missing Damper Tube

[Tom9589]

I understand that the Muntz M-169 chassis was produced in two versions: a 16 tube version with a damper tube and a 15 tube version without a damper tube. In the damper's place, Muntz used a power resistor and a capacitor.

Two questions:

1. How well did it work?
2. If it worked OK, how come other manufacturers didn't copy the circuit?

Thanks.
