On shelf at left is an EICO 720 transmitter (built from kit) , 90W DC input to a 6146. On top of the EICO is a Hallicrafters S53A receiver and on top of that is a 25W plate modulator (built from '61 ARRL Handbook), 2-6DQ6Bs in push-pull. Switching the CW/PHONE switch on the modulator to PHONE inserts the modulation transformer  into the 6146 B+ circuit. Switching to CW shorts the modulation transformer allowing Class C CW. In the center is a Hallicrafters HA-5 VFO and on top of that is a 5 inch speaker. On the right is a Hammarlund HQ145X receiver. Hanging under the shelf on the left is a box containing an antenna switching relay, a receiver muting circuit and an RF ammeter. Switching the EICO from Standby  to Transmit activated the antenna relay and muting circuit. Later on in the 1960s the box was eliminated and an electronic TR switch was built, allowing full break-in operation on CW.

Screwed to the front edge of the shelf on the right is a switch plate with 1/4" phone jack and RCA phono jacks for headsets. A toggle switch selects phones or speaker. A rotary switch selects Receiver 1, Receiver 2 or both receivers at once (allowing the operator to listen to music while copying Morse code). On the desk at left is a Vibroplex Original bug. The electric fan kept things cool. It was really hot in that closet with the door closed!!! Antenna was a Gotham V-80, 23 feet of Al tubing with a large inductor at the base, tapped for 80-10M.
