? At the anode-resonant freq. In a TL-922, this is c. 130MHz. In order
to optimize the double resonance, one needs a vhf suppressor with:
1. diffenent amounts of L in each branch
2. minimal mutual magnetic coupling. . whew
3. roughly equal current so that one resonance does not obviate the
other. .
