I used to work for RCA at the Smirnoff Labs, and around the early 80's CTC101 sets had the infamous integrated flyback problem. Seems the problem was that the very high voltage winding was split into 6 sections, and diodes were supposed to go between each section, but someone cheaped out and only used 3 diodes and pairs of windings were joined together. This made for higher AC voltage at each diode, diodes were fine, but they used sharp edged stakes as terminals to connect the winding wire and diode leads. This made for excessive corona. And the epoxy eventually failed, shorting the flyback and taking out the horiz output transistor. Was a warranty disaster.
