Thanks, I ordered oneTomswork wrote: ↑Mon Jun 29, 2020 6:47 pm Oh sorry if you have a signal generator you can just feed a horizontal signal in and check along the test points to just before the fly back. Will reveal weak parts. And yes some of those flyback could stay charged for years and still burn a probe tip. Samsung and Philips loved them. Must of the time you were just waiting for the tube to heat things. The part your showing looks like it charges the tube before the horizontal signal starts. The power supply is the spot with the capacitors and the regulators. That take the beating the do not cool well.
These can be got and ebay they work jds6000

I just remembered some crt history. The extra flyback were run off the crowbar transformer to but a charge on the tube to keep the x rays down until there was a horizontal signal. And it made them come on fast

...or "it got rejected by customs" or "customs are very strict these days" are just the standard excuses that Chinese suppliers use for everything that doesn't arrive for whatever reason.
