Ameritron AL-572 for sale: Ameritron AL-572 For Sale - New Asking Price
I have an Ameritron AL-572 amplifier (serial number 11473) for sale. This amplifier has been my backup for the past 10 years or so; it has been used very infrequently. I recently tested it briefly and it was putting out 1000 watts on 20 meter CW with about 70 watts of drive. It is in good physical condition. It is working but due to its age I am selling it “as is”. It is currently wired for 220v AC but can be rewired to 120V as an option.
I am hoping for pickup in Southern California, and am offering it for local sale for $700. I will ship if I have to, at buyer's expense (about $200 to the other side of the continent). I will have to take the 4 572b tubes out and pack/ship them separately.; Listing #1754661 - Submitted on 01/03/26 by Callsign K6NR, Modified on 02/02/26 - IP: ip68-4-255-171.oc.oc.cox.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
