Only once in a great while will a manufacturer start with a clean sheet of paper and design from the ground up a new amplifier. Most amplifiers are a follow-on design from a previous model which nibbles around the edges of the basic design to add a few new items to the old design.

The Dedicated RF revolutionary new HF / VHF amplifier uses a state of the art microprocessor for all operational and diagnostics functions. The amplifier RF input network senses the frequency and automatically tunes the proprietary variable Q input Pi network for proper tube matching within a fraction of a second. This maintains flat input VSWR and maximum RF transfer efficiency to drive the 3CX1500A7 triodes while reducing harmonic output from the amplifier.

The dual input means the contester or casual operator can use multiple transceivers to drive the amplifier - including your HF or 6 meter transceiver of choice. The microprocessor controls all functions in the amplifier including critical warm up functions, temperature-controlled power-down functions, band limiting, bias control, voltage switching, band switching, keying and diagnostics. In addition, the station control can be accomplished with a remote touch control screen module that can be remoted by a fiber optic cable or mounted to the amplifier itself for desktop use. In addition to the touch screen, the amplifier can also be operated from a desk top or laptop computer, being compatible with Windows or Macintosh OSX operating systems.

The unique design of the constantly variable inductor means that the ideal, most efficient impedance match from the tubes to the antenna load can be made. Vacuum variable tune & load capacitors reduce the chance of capacitor arc over and maintain the best circuit Q for power transfer. Power losses in the efficient vacuum variable capacitors is minimized for more efficient operation and reduced heating.

In addition to increased efficiency, the harmonic output is greatly reduced with higher Q tank circuit, and the built-in addition of low pass filter circuits for HF and 6 Meters. The HV power supply uses a custom Torodial AC transformer for more efficient AC step-up with a full wave bridge for DC HV generation. Auto-sense AC primary voltage is standard for US & many foreign voltages. AC ripple is reduced with ten (10) low ESR 500v capacitors.

Our amplifier utilizes an upper / lower split-level design, where the power supply is located below the RF section, with the lower-mounted dual-blower charging the tube plenum above for quiet operation. Intake filtered air is circulated through all parts of the amplifier for efficient cooling.

Commercial units will be available firmware-unlocked for full spectrum coverage.
