 FOR SALE: Heathkit HA-14 w/HP-24 PS  
Selling a Heathkit HA-14 "Kompact Kilowatt" (input) power amplifier and matching HP-24 AC power supply. The 572B finals are soft as I'm measuring about 400 watts output PEP on 75m and 20 meters, and 300 watts PEP on 10. Original paint and wrinkle finish, original knobs, very clean condition. HP-24 AC supply has a new Harbach PM-HP-24 Power Supply Module installed. Power supply is wired for 120 VAC. Original manuals for both HA-14 and HP-24 are included as well as the more difficult to find radio cables and high voltage cable with Millen plugs on each end.
Asking $450 plus shipping. It is shipping in two boxes as the power supply is pretty heavy while the amplifier weighs very little. I plan to use Pirate Ship UPS or USPS. If you pick it up, I can demonstrate the amp otherwise it's sold as-is. 73, Scott WA9WFA
