For Sale: two (2) 4cx1000 tubes: From an estate. These tubes were used to power a Collins 30S-1 amplifier. I believe both to be good but have no way of testing. Selling for the widow of the deceased ham who has already sold the amplifier. They performed very well when installed but I believe they were pulled because the owner wanted "more power" and installed 4cx1500's, which were sold with the amplifier. Asking $325 or best offer, shipped and insured to anywhere in the continental USA. Will accept personal check (must wait for check to clear), postal money order or Paypal (not Friends and Family).; Listing #1761432 - Submitted on 03/09/26 by Callsign W8QW, Modified on 03/18/26 - IP: dyn-149.19.222.129.hrvl.mi.homeworksinternet.net; Click to Contact -- Send this Ad to a Friend
