Once we had cameras functioning in two studios, we turned our attention to a couple of Norelco PC-60s locked away in a storage room. There they sat, resting upon a couple of (leaky) TVP pneumatic pedestals. At that time, the shop was a small room next door to Control “B”. The students must have been gone for the summer, because we took over most of studio “A” with a vow to get them working and on-line. As part of writing this post, I located Greg McMurry. He was one of the engineers who preceded me. He told me that he had procured these cameras in hopes of “going color” after a false-start involving a couple of RCA TK-42s.
The cameras had been in the storage room for so long with irises open that an image of the storage room door was permanently captured in the pickup tubes of one of the cameras. This set me off on a “Plumbicon collection campaign” that taught me how generous some broadcasters are when it comes to helping a fledgling educational facility. 
The above photos were taken as Bob Swanner dug elbow-deep into these cameras with some serious dedication to getting them operational. I believe the blue chassis are after-market encoders, and that the original Norelco encoders were not part of these camera chains. Besides the Conrac RHA monitor sitting on the floor, there is a Ball Brothers (Miratel) monitor in the background. The Mason jar manufacturer was also into video monitors and other equipment. The cameras likely put out video when first fired up, but it is for certain that they were in need of tubes, serious tweaking, all new registration pots, and about 2 gallons of contact cleaner.
In speaking of the generosity of other broadcast engineers, our search for “gently used” (this means pin-holes smaller than .22 cal bullet holes) Plumbicon tubes took us to WJET-TV in Erie, Pennsylvania. There, in a quonset hut on the outskirts of town…and directly under the transmitting tower, we were given at least one additional PC-60 camera chain, manuals, boxes of Plumbicons, and genuine “fellow broadcaster hospitality” that you remember for the rest of your life.
