Bob Let me know what u decide on. I'm running qrp AM and need every ounce to be intelligence. I can't waste power to be hifi. Was your ckt similar to the Eico modulator clipper? I assume you will strictly use tooobes? :-)

I had a tube speech processor back in the 60's. It was a classic clipper/filter. It worked very well. For a lower power transmitter like the smaller Heath DX units you can increase the voice level clipping and filtering there by generating a higher modulation index without over modulating. And if properly set you won't exceed the legal limits. I am going to build another one for my current DX-60.
