Drake L7 HF Amplifier:
$1,352

Here is one of my Drake L7 Amplifiers. This unit is in excellent working condition and includes the required L7-PS power supply unit. I will ship the unit in two boxes: one for the power supply, and one for the deck. Transmission tubes will be shipped in place, but will have additional protective packing around them (REMOVE BEFORE USING). Drake built these amps back in the day when the rules were 1000W input on CW and 2000W input on SSB. These amps are about 60-75% efficient. So that means about 750W output on CW and 1200W+ PEP on SSB when properly tuned and powered via a 220V mains. This unit will function on 110V mains but at slightly reduced power. Also, there are many pictures of these amps with "blue" meter faces rather than the "white" meter faces as seen here. In actuality, they are all the same as the "blue" look is simply from a thin plastic film slid in front of the meters. Remove the plastic film and you have the white faces. The power supply typically sits in the floor away from the operating position. This particular unit is already wired for 220V mains.


Items included:


- Drake L7 RF deck

- Drake L7-PS power supply

- Original print Drake manual

The finals in this unit areEimac that appear to be the original set. I tuned this amp a few months ago and got 730 Watts CW outputon an LP-100A Wattmeter, which is well within the range of what one would expect. I'm also including a copy of my handy-dandy, step-by-step, never-fail cheat sheet on "How to Tune a Drake L7 Amp." It's not in the running for the Nobel Prize in Literature, but it does make tuning an L7 relatively easy. It's basically the tuning instructions from the Drake manual but in a more concise, step-by-step form with additional steps to correctly adjust the ALC control during the tuning process, something not clearly detailed in the Drake manual.
