Predicta 17" HV question

[Phil Nelson]

After a few more tweaks, I'm declaring this one finished.



Part of the difficulty I had with vertical linearity is that someone had adjusted the vertical centering as far off as it could go (perhaps to compensate for some aging component in the past). With that back in a sensible range, it was a piece of cake to make the vertical correct using the other controls. I always feel better when controls are somewhere in the middlin' range rather than maxed out.

There's an article, too:

In researching, I found Philco's original patent drawing for the tabletop cabinet:



Interesting that the original concept had more knobs on the front, and a slanted control panel.

On to the next project! Thanks again for the advice.

P.S. I'm missing an end cap for one of the support arms. If anyone has a spare, contact me at http://antiqueradio.org/contact.htm .
