The late 60s Zenith's with all film caps, silicone flybacks, and lytics not much different from modern ones (ignoring size) are about as you describe a hypothetical modern set, and are fairly long lived.

Hehe, spikes and noise... here sometimes a very huge spike occurs in the waveform, making noise in EMI filter, trafos, even in some motors...
And, some years ago, I worked at a transformer factory, with plenty of motor inverters: the mains waveform at that place with full production run are almost a squarewave (with rounded corners...)
Ahh, those modern appliances...
