polaraman, I don't have the camera with me but will post it this week when I get a chance.

SAMS does show how the color socket is wired/installed. There is also a switch to go from B/W to color. The control diagram shows it to be on the front of the set.

(1) Re: "...sufficient light...?" It seems a 21-in. tube would need the scanning area reduced for the accompanying boost in light and so a reasonably sized wheel could be used.

However, (2) "...a switch to go from B/W to color." the switch is a puzzle. Does it change the sweep width/height? Maybe the set has a dual-frequency flyback. That'd be a find.

Pete,

I think the Hallicrafter's marketing dept.,and other manufacturers sticking color labels and adapter plugs on their sets, saw an opportunity to move a few more sets out the door. Just turning the set around, a salesman could show the potential buyer this flashy label and close the deal.The customer probably thought he'd be able to receive color the moment it became available. I'm sure the salesman didn't argue the point.

It still goes on today with HD or is that HD ready?

Polaraman,

I do not have a copy of the Sams 165-6 for the Hallicrafters. I would like to know what electronic function the B&W/Color switch performs. Could someone post a scan of the Sams schematic page for that set?

Thanks!

The BW/Color switch (in the color position) basically disconnects the contast control from the video output circuit and routes the cathode of the video output to pin 5 of the color socket. It does nothing to the size of the picture.

Hi there Steve K. Thansk for the info on the color / B&W switch. There goes my hopes that the set used a dual-frequency flyback.

a lot of monitors today ARE HD ready, just need tuner & progamming. There must of been a lot of dissappointed people years ago when the factory color converter didn't materialize,-- especially if this feature was a sales point. A commmercial and egineering dead end for sure.

Here are pictures showing my Admiral which did not get the socket. Note that the build date stamped on mine is in Nov. 51.

Well, as the last CBS Color Television System broadcast was:

Oct. 20, 1951, 2:00 P.M. “Football” – North Carolina at Maryland (from College Park, Md.)

Admiral acted quickly to remove that Color Conversion Socket from its sets.

I think we have that sams folder...will try and look at it tomorrow.

Figured I'd post a pic of the date code, and while I am at it a pic of the set working. It had a bad doorknob cap; worked before but with the sound of arcing. For some reason there is this odd attraction to placing my hand on the metal crt bell while it is operating! I'm glad I have self control!

[David Roper]

A little bit of carelessness is all it takes. Chassis plugged in on the bench, standing facing the tube while reaching across to the framing adjustment rod, arm brushes the CRT lip and ZAPP! Good thing I was wearing a sweatshirt.

I bet that Admiral was glad that the CBS system bit the dust. That way they had an excuse if any customer ever called them on that color conversion: "Sorry sir, but that color conversion socket was based on the CBS system which is no longer used. Blame the Funny Cookie Corporation."
