Westinghouse K840CK15 Restoration

UPDATE, JULY 18, 2019, DAY 348

From Mike: “ I have made center convergence! YAY! The crt is not the best and the red is definitely weak compared to the green and blue. The blue is the strongest. I have not achieved good purity yet but I am still working on that. The purity control is all the way to one end and I may have to do some circuit modifications to get it in to a better range. I will be sending photos and data pictures of the succsessful center convergence later. But for now, I will send pictures of a POP and SMOKE that happened tonight. This may very well be a good commercial for “Depends”. It got my attention when it happened. I was merrily going along, doing adjustments and evaluating things when “KABLOOEE”. Then SMOKE from the rear of the chassis. The good news is, it is not disastrous. One of the AC line capacitors “let go” and exploded. These rarely ever give any trouble. But this one did. So I will be replacing both of them. They are mainly installed for line interference. Marshall, you are probably very glad that this did not happen at your house, and so am I.

Onward! “
