It took a Pandemic to get me back into this.

that have been lead free solder in my field for years now, gotten used to it, what i really HATE is the "no clean" flux, because it's not, as in NOT CLEAN! and it does a crappy job, and the " water soluble " stuff, if you don't clean it all off correctly the PCB will dissolve into mush in 1/2 year.
But the biggest problem I have seen is cratering, I get a item back RMA that has been in the field working 3-4 years and fails, remove a BGA and half the pads come off stuck to the IC...

It came out great, with a hitch.

I had the chassis working great, then I accidentally left the Zoom switch laying cross the chassis and shorted it to something, had some smoke and the picture was too short. Let it sit for a couple years while I worked on the cabinet, got that done, quite happy with the results, not OEM, but nice.

Back to the chassis, I couldn't find anything burned or out of whack, then I managed to get too close to the Flyback while I was turning the yoke, my hand got zapped a little from the top of the 1B3, when that happened the picture suddenly went trapezoidal, not really sure why that should happen but it's a sure indication of a shorted yoke.

I have a bunch of used yokes, none labelled, it should be the same as an early RCA DY1. I tried a random yoke from my collection and got a full height picture, but far too narrow, possibly because the capacitors and resistor in it are wrong. I stopped at that point, I know it needs a yoke so I will get back to it as soon as I can find a DY1, or RCA equivalent.
