Westinghouse K840CK15 Restoration

[etype2]

UPDATE, APRIL 29, 2019, DAY 272

On day 272 of this restoration, we have color!

From Mike: “Greetings! Please share my excitement in the event of first color on the old Westy! The color is not “correct” color yet, but it is color. This is a major milestone of progress in this endeavor of restoration. There is still much to do. I need to figure out what is going on with the proper phases to make the color correct. The dead color circuits turned out to be a failed filament in the bandpass amplifier tube. All tubes were tested several months ago and the 6BA6 tube was fine then but it evidently died soon after. No wonder the voltages checked OK but the signal was not passing.

Cheers, Mike”
