Listen to this and imagine beautiflul dressed women and men in a googie styled lounge based in an amzing art deco city and watching the landing on mars by a retro futuristic designed rocket crew on curved hollow screens 🫠🫠🫠🫠... in a much better parallel universe.😭😭😭😭.
When I was a kid I remember old color TVs had a problem staying in the right colors. People's faces slowly went from flesh tones to green. You had to constantly adjust the colors, or live with people turning green. Sometime around 1970 color TVs had automatic fine tuning and the color of people's faces stayed the same throughout the whole show.
The tuner in '58 was available as an option-it you wanted it, it would drop into what would otherwise be the record bin on the left as here. Notice how it was switched out before playing the record-beautiful console!
Wow! I have replaced motor start caps in my four Sony Reel to Reels. But I just soldered them to original wiring and wire tied and electrical taped them in place. Big difference to see how a TRUE ENGINEER does similiar work! I would like to see some performance testing. Frequency response before and after, wow & flutter, speed calibration?
Having been in the TV Repair business I started in 1978 , I was in the business until 2017 when the industry became a throwaway business. However, I remember working on many models from the 60s and 70's can still remember the smell of those older tvs ... I miss those days sincerely. I wish I would've saved all the tubes the I accumulated over those years.
Beautiful Zenith console color tv. My father bought the same model minus the Space Command feature. I was the official channel changer. I believe the year 1970 saw a exponentially higher increase in the number of color tv's in the USA.
I see that Zenith chassis still has some white "Elmenco" caps on it (which may have tested OK but are original and may fail later) and not too many leaky/shorted bumblebees that needed replacement. A 60+ year old B&W tube TV producing a good clean picture today with no smearing or cloudiness has to be a testament to quality. I'd like to see a Philco Predicta do that!
This radio has a problem on the tuning printed circuit board resulting from dissimilar metals with the rivets that connect the top side printed circuit to the printed circuit on the bottom side of the PC board. Soldering is not sufficient. The fix is to solder jumper wires on the top side of the board to replace the connection made by the printed circuit on the bottom side. Shining a bright light through the bottom of the board shows clearly where to solder the jumper wires. This is the RF amp and Local Oscillator circuit so it will require alignment. Operation without repair may be intermittent.
