Restoring a Vintage Color Television Set

15GP22 REBUILD STORY

June 10-11 2008

At 4-o'clock in-the-morning of June 11, 2008, Scotty opened his oven.

Inside, John Folsom's now-cool 'rebuilt' 15GP22 sat firmly in its vertical perch.
Everything was there, but not everything was right.

The day before, it had been 600-degrees Fahrenheit inside that oven when Scotty's thirty years of CRT rebuilding experience detected an errant sound.
He quickly cancelled the automatic pinch-off and cathode-activation procedures.

The evacuation tube had failed at the height of the baking temperature cycle.
It had snapped off where it connects to the button.

Thinner and more frail than its huskier counterpart on the right, the new tubulation did not withstand the stress.

Since the new cathodes in the delta gun had not been activated, the gun can and will be used again when a stem with a more robust evacuation tube is manufactured.

The open neck was covered to keep dirt, bugs, and moisture out until the next rebuild attempt.
