Max,
i know the Push-Pull should be at a 50th sub-harmonic frequency of the Kacher / Grenade resonance frequencies, so i was tuning the Push-Pull to be around this value (24.8, 25, etc. kHz), but never i saw this modulated signal yet, but as i mentioned above, i will do some further fine-tuning.
Thanks for the Geo video's, but as he has not yet showed a self-runner, how amazing his effects are, it does not necessarily mean he is/was on the right track.

Itsu, See if you have resonance at 122.9k or there about.
Point of correction, I edited mine to 24.58kHZ that's the actual 50th sub-harmonic frequency of 1.229MHZ.
Be sure you have two pot on your PP cct. One for fine tuning. This enables you to pick the exact frequency. And one thing is your "CT" in your TL494 board Timing capacitor should be a very good one , this is in order not to drift away from res. freq. after awhile.
