The 1945 launched USN tanker I served on 1961-2 (USS Wacamaw AO-109) had a
distribution/patch panel on the wall of the radio room. It used a 6AB7 as a
cathode follower. Built by GR and used the famous GR quick connect plugs and
jacks. Any radio could go to any antenna. We had 2 long wires, 1 36'
vertical and 1 12' whip for receivers. A lot of gear for a tanker but we
often carried the Admirals flag as we were the senior ship in the Service
Fleet (SERVLANT).
