The SPC Supertuner is designed to handle high power either feeding coax or balanced line. The ATU has wide-spaced capacitors, a silver-plated main inductor, and large ceramic switch.
All these are heavy-duty components to handle powers up to 1500W.
The SPC Supertuner has an instant bypass mode that can be used with coax or a balanced feed with the balun left in the circuit.
The balanced line is fed from a large double toroidal type transformer which is insulated with special fiberglass sleeving to reduce any chance of flash-over between windings.
The large VSWR/ Power meter reads 150W full scale on low and 1500W on the high position.
A 12V DC supply is required for the operation of the relays and also to illuminate the meter.
