Bear in mind that any design of anode lead suppressor can only work
given a low(ish) impedance path to ground at the tuning network. If by
resonance or design the network appears open cct (or high impedance) at
soem frequency, the voltage gain (gm x Ra) will be high - a good
candidate for an oscillator.
