Hi!
I want to build a modulated tweeter. It should play quite loud.
Thinking about the modulator i got an idea. Would it work if i use a circuit of a Single Ended tube amplifier for modulation?
I would replace the output transformer with a simple resistor and tap the signal from the Anode of the driver tube and feed it into the G2 of the tube that runs the tweeter. It would be possible to adjust the G2 voltage of the tweeter tube.
Circuit example:

Any ideas? Will it work?

Thanks in advance.

RateReducer,

Tesla Coiler Sue Gaeta built a very nice VTTC audio modulator about 10 years ago. You might be able to get some ideas from that.

Here is the last known address of her website.
