Another Motorola VK-106 restoration attempt

[pdr-fml]

Please let me know if this link works it is a MS onedrive link to a video of my Motorola up and running. This is from a few years ago and I still have some work to do on it and unfortunately the crt is weak but sound is real strong. Let me know if it is not appropriate to have a link like this.

It looks decent. If you adjust centering by moving the focus coil I think you might be able to call it done.
Picture looks decently bright for a set of that vintage in a well lit room. (TVs were expected to be watched in a room that was dark or lit just enough brighter than dark that you wouldn't trip over an unseen otoman on your way to the fridge).

Yeah it is pretty crooked. That crt test well into bad on my recently acquired crt tester so that goes to show you can sometimes still have enough there to make restoration worthwhile.

A lot of testers made in the color era (post 1953) have their emissions scale calibrated for color CRTs. Color CRTs have a shadow mask between the gun and phosphor that absorbs %80 of the gun emissions preventing that much from reaching the screen. Color tubesthus need a LOT more emission for a given screen brightness. I've tested a lot of tubes with my tester and kind of know where in the bad zone a monochrome tube is really going to be bad at, and where in the bad zone it should work OK.

[EDIT] Somehow my post on a color Motorola thread elsewhere ended up here. Please delete this post.

Ain't that the truth. Hamfests are likely the last place on the planet where sellers don't have their head in the clouds dreaming that their obsolete electronics is in high demand.
