For Sale: Ameritron AL811 with 572Bs: Lightly used Ameritron AL811 amplifier in good operational and physical condition with 811s replaced with 3 matched DX Engineering 572Bs. Used on 40 and 20 meters only. Never driven to more than 350W CW and 400W SSB because my antenna is in my attic. 10/12 meter modification has not been done, but it is a simple "cut the green wire" mod. I will included instructions on this mod. Wired for 120 volts but can be converted to 220 volts by a simple jumper change and replacing the fuses.
This is a heavy piece of equipment, so I would prefer a local pickup. Alternatively I would meet/deliver within 100 miles of Charleston, SC. $650 for either option. Complete with instruction book.
I accept PayPal or Venmo electronic transfers but buyer has to pay fees so I net $650. Otherwise cashiers check or cash.
Thanks for looking,
