They're not that scarce...

Thordarson made flys for the 16, and they were superior to RCA. RCA's weak point were always the flybacks, from day 1. They used that same crappy design from the 16 thru the 40. It was the coating they used. If it got the least bit hot, it would start melting. Thordarson used a heavy black rubber coating that did not melt. Back in my service call days (late 70's early 80's) our shop would be humming with flyback replacements, ESPECIALLY in the summer. Not everyone had AC (hard to imagine now) and these sets were daily watchers. Once the Nebraska heat and humidity came up, that was it. I think the repair back then ran $150.00 (which included labor) IIRC the flyback, 6JE6,6DW4,6BK4,3A3,2AV2. We never let the set out of the shop with the original high-voltage sweep tubes. If I never see another CTC-38 again, it will be too soon. LOL!
