Drive is configurable via jumpers from just a few watts to around 40-45 watts. I regularly contact K6MYC in Fresno from Torrance at a distance of 234 miles on SSB with this thing. It does not include a power supply but power supplies can be purchased on eBay or Amazon. The Mean Well RSP-2400-48 is a perfect match and available on Amazon or an HP blade power supply off of eBay for under $100. Original manual also included. If interested, I can email you a video link so you can see the amp in operation. Key Specs: - Compact cabinet (6x12x12 inches) - VSWR and over temp protection - Analog metering for voltage/current and LED bar graph meters for forward and reflected power levels - LNA power feed and front panel on/off switch - Front panel switch for turning on external power supply - Comes from a non-smoking, non-pet home I will not sell without a phone conversation first. Message me for my phone#. Price is $2400.

I have had this tuner since end of December, tried it out to make sure all was well, and it sits on the shelf. Thought about getting an amplifier but that never happened so really do not need this tuner. Awesome tuner but excess to my needs. $650.00 Price FIRM. Original Box, Manual. Postal Money Order, Personal Check or Paypal + 3% No Trades. Thank you for reading.
