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

Tuners antenne 7 MHz with only one CV
A 1: 1 ratio balancer made with a T200 toroid makes it possible to connect the transceiver with a coaxial cable to the symmetrical circuit formed by the chokes and the CV. As the isolation of the CV is weak
