Westinghouse K840CK15 Restoration

[etype2]

UPDATE, AUGUST 27, 2019, DAY 388

From Mike: “Greetings Marshall. After spending a few nights doing some modifications to the convergence circuits I am now claiming that it is as good as it will ever be. You might recall that the Vertical Dynamic Convergence transformer that we purchased is not a direct replacement for either the CT100 or the Westy, but an averaged value to satisfy both. The blue near the top continues to be a problem but it is better than when I started. I will get a screen shot to you soon. On another note, I need to order another set of H.V. rectifier tubes to try because the high voltage seems to drop a bit after the set runs for a while, like 20 minutes. It starts out fine but drops to 18 KV or so after a good warmup. These tubes are 1B3’s and it is a set of 3. I replaced them with a matched set of Mil Spec type early in the restoration process. Then there were a series of issues with arcing that I had to deal with so what I am hoping is that perhaps one of them suffered some damage during those times of arcing. I won’t know until I try new ones. I have ordered them but was unable to find Mil Spec types,, Just New Old Stock. Stay tuned!

Regards, Mike”
