Only one channel is shown, both channels are identical. The input and output RF filter coils and capacitors should be build on the RCA jacks, keep the leads short and use coax to run the signals to the circuitry. The circuit should be build inside of a metal box for shielding, use metal boxes for all transmitter circuitry.

To align the clipper put a low level signal into the circuit and adjust the 10K trimmer so that the LEDs do not light. If you have a scope, adjust the trimmer for no output on pin 7 of the 1458 op-amp. When the circuit is adjusted properly the LEDs will l
