Westinghouse K840CK15 Restoration

[etype2]

Update from Mike, December 30, 2018. Day 152

Greetings Marshall. We are finished with the bottom of the chassis, at least FOR NOW. Picture #1 is the top of the chassis again, and it shows nice clean capacitor cans that have been replaced. The rest of it still needs a lot of cleaning and yet, some more components replaced. For now, it is time to rebuild the tuner since the lubricants have long ago turned to something more like plastic rather than grease or oil. But first, I have snapped a picture of the “HUE” control that you speak of and have asked it to be moved to the front of the chassis. This is not going to happen. The HUE control is NOT a POT. It is a coil. There is a flexible cable that is manufactured to fit the top of the slug of the coil and that is their method of changing the phase relationship of the colors. I do not see a “good” way to move this control. It would be problematic since the controls on the front panel are all below the “plane” of the chassis. Anyway, Picture #1 shows this issue. Picture #2 shows the chassis with the nice new electrolytic cans and a “somewhat” dirty chassis. This will be cleaned up a bit during the next restoration phases.

Picture #3 is before the tuner removal.
Picture #4 is the tuner removed.
Picture #5 is the cover removed and you can now see the corroded condition of the contacts on the channel elements.
Picture #6 Channel strips removed.
