Commander HF-2500 Linear Amplifier - HAM Radio HF Amp:
$2,025

I believe the HF-2500 Commander may be the longest in-production Ham Radio HF amplifier model utilizing indirectly heated cathode, metal-ceramic tubes. It has been on the market since 1990 and has developed a grand reputation over time as a reliable, compact, lightweight desktop legal limit++ powerhouse that doesn't break.Over the years I have heard many Hams on the air make casual comment that they were using a "Commander", when asked. In the 90s I learned that "Commander" was some sort of an established Ham Radio linear amplifier legend for power, reliability and quality. This unit has been used extremely lightly and is in near perfect condition.The current going price for this amplifier is well over $3,000, and it is considered "The Mother of Lightweight Legal Limit++ Ham Radio Linear Amplifiers." The original manual is included.

This amp is a class AB2 linear power amp, designed for operation on all amateur frequencies from 1.800 Mhz thru 21.450 Mhz. Two Eimac 3CX800A7 ceramic-metal triodes, configured in parallel grounded grid mode, allow for conservative legal limit operation at 1,500 watts. A pressurized forced air cool chassis, including the High Voltage Power Supply, insures cool operation with high duty cycle emission modes. The output circuit utilizes extra heavy duty component with reduced ratio vernier drives on all tuning controls. Easily accessed rear panel controls allow for operator adjustment of input VSWR and ALC. An automatic time delay circuit, a tube-life extending feature, insures proper cathode conditioning before RF drive can be applied. Protection resistors, located in both the high voltage B+ and B- circuit, protects the tubes in the event of an internal tube arc. Metering functions include plate voltage, plate current, and grid current.

Serial#: 362

This unit was used in my father's radio room, a smoke-free environment, and never moved. He babied all of his radio equipment, and kept it in tip-top shape. Heisno longer able to spend time with his radio equipment, and has given it to me to sell.

I plan to remove and ship the tubes and transformer separately. The instruction manual includes directions on how to re-install both of these appliances.

You can offer with confidence, I accept returns for a full refund within 7 days if you are not satisfied with this unit's quality.

Please contact me with any questions you may have!
