    As a reference for these projects, variable capacitors of around 410pf, common in valve receivers, are in most cases perfectly usable for low or medium powers


Tuner W1FB scheme Compiled
    Variable capacitors have a capacity of 200 pF, for a power of 2 kW at the peak, the gap between the plates should be about 2 mm. L1 - coil with slider, maximum inductance 25 mH. L2 - 3 turns of 3.3 mm bare wire on a 25mm mandrel
