Okay! Let's see how this works. I combined everything in what I hope is the right way. The big question marks are the coupling and bypass caps. Also, I would like to configure the input for a low-Z dynamic mic, so some massaging is in order there I'm sure.
What do you guys think?
You'll want to make sure that the 807s have the right voltages (and load impedance) for class AB1 operation, as the resistance-coupled driver
cannot drive them into AB2. The high plate load resistors on the first two stages might limit your highs somewhat; I am not sure how much.
I personally don't like the purposely-unbalanced driver plate resistors to force higher positive peaks -- that adds unnecessary distortion. In my view, it's better to just design a modulator to faithfully reproduce whatever waveform is fed into it (then you can do all your audio shaping, if any, in your external audio preamp chain, and the transmitter won't alter the sound you've achieved). The male voice usually has plenty of natural asymmetry anyway; sometimes even too much, hence the good sales of the Kahn Symmetra-Peak among broadcasters.
There are many schematics for low-Z microphone preamps out there, the output of which could be fed into the hot end of the gain pot.
I would also add that an audio signal generator (many computer programs can do this) and scope are
essential for seeing and understanding what your new modulator is actually doing.
There's a whole world of audio ideas out there, as I am sure you're seeing, so build and explore and learn and enjoy.
With my best,
