Harry's at it again, Westinghouse this time

[Eric H]

Ultra Rare 15" Westinghouse on eBay.
Tube is definitely down to air.

He has an RCA CTC-11 on Ebay, as well.

Won't be bidding on this one, I still have the prototype to deal with and this Westy has a bad tube.

Andy, au contraire, TV was in Texas in the early fifties. In Beaumont that meant a 50' mast with two yagis, a big one for Channel 2 Houston, and a little one for Channel 11 Galveston. Then in a couple of years Beaumont and Port Arthur got stations.

"color hold", I like that. I wonder if it has color afc or that control just bends the crystal like adjusting the osc coil.

Interesting

Well the ebay pictures tell the story. It's all there. Anyone got a spare, working, 15GP to sweeten the deal? I wonder if Marlin Mackley is still keeping track of these sets? He hasn't updated his site since 2004.

According to the ETF database there are 17 confirmed survivors (including this one) with an unconfirmed 18th and yet another pre-production prototype at the museum.

A fascinating set from the technological viewpoint, but dang is that cabinet ugly.

Just my $0.02.

This set has no crystal. The color hold control locks the color sync. Once it is set it is fairly stable.

I acquired my Westinghouse a couple of years ago from a lady that
Lives about 10 miles up the road, I recapped the set and shortly
After replaced a defective on/off switch.that all that was done.I have
Had 2 ct100 over the years and the westy has better picture and
Color. It's unusual color lock works well. I noticed the set that Harry
Posted has a chassis at the bottom also, I do not--- is that an audio
Amp?the set is large and kind of ugly -- but I love it.

I would think at this stage all the early color sets all used the same tubes and phosphors and classic chroma demodulator gain and phase. Once phosphors shifted and people noticed that flesh tones looked different than they should designers started to spread the R-Y and B-Y demodulation angles and play with the gain ratios to get the color rendering they liked. Later went the color temperature started shifting up gains changed again.

Then came the boom of auto correction circuit. ACC was the first in the CTC-4 i think?Then came auto flesh circuits they pulled the phase of the chroma demodulator for a color close to flesh even closer. The auto flesh circuits that operated on color difference signals were less obnoxious than those that pulled the color sub-carrier.

Does anyone know if the Westinghouse have an ACC circuit?? Does it use a standard demodulator circuit?

Yes, no need for non-standard gains and angles since they all used the same phosphors.

Here I disagree. The hue pulling circuit could affect hues around flesh tone without killing greens, cyans, and blues. Effectively, all the linear matrix type auto flesh tone circuits did was to decrease the Q axis gain, so you tended towards either reddish orange or cyan. Depending on how far the manufacturer went with it, you could end up with "the tan cowboy on the brown horse riding into the orange sunset" while trees and grass got desaturated and had a tendency to turn brownish. Engineers never used a set with that "one button auto color" engaged (well, maybe their family members did), preferring to adjust the color when necessary.

The thing about RCA's auto color that I didn't like was the setting of color level based on average chroma level. This resulted in the color level turning up or down based on scene content, and I often saw obvious failures when the scene cut to talent wearing bright red clothing. It did result in "calendar color" (somewhat oversaturated on low-saturation scenes), which the public seemed to like. I PO'd someone I interviewed with at RCA once when I told him this was not a good idea in my opinion.

The hue pulling circuit was invented by my colleague Ted Rzeszewski at Motorola. For some reason, Motorola never used it, but licensed it to RCA.
