Back to TV discussion, I've seen many over-designed sets. With tubes, the color demod circuitry can be a pain to trace out and repair. but the power supplies. I notice that as TVs got lighter over the years, the switching supplies got more complicated in general. No longer do we see a big transformer with secondary taps and smoothing capacitors connected to diode rectification. Sonys had a lot of proprietary ICs in the Trinitron PSUs which made the set BER for the consumer. Shame to junk a set when the tube is still in good shape.
