'56 Hoffman Color-caster - Videokarma.org TV - Video

Cruiseomatic · #1 12-27-2009, 01:31 AM

I just got a '56 Hoffman Color-caster that needs an electrical restoration and tube re-build. Took the cover off,Good night.....How in the world do I do this? The chassis looks almost impossible to remove and so does the tube......Does anyone here have any experience with these sets? Thanks.

I would start seeking a Sams Photofact for the set - they often gave instructions on pulling the chassis as well as the other information that will prove invaluable in your restoration.

There isn't a Sams on those, if it has the upright chassis or if it has the 19" CBS tube. However, if you didn't notice, the whole side of the cabinet comes off in one piece to expose the bottom of the chassis. Inside that cabinet panel is a schematic (or at least there was when the set was new). Both of mine have them, but they're not accessable at this time or I'd get you a photo.

The blond modern one has a visible panel that is just the size of the chassis, but the traditional mahogany cabinet version has a secret release for the whole side of the TV. Look below the chassis shelf, and you'll see a slide bolt pointing downward. As far as I remember, that one slide bolt releases the whole side.

If yours is a later model; late '56 or '57, it may have a different configuration. The early one has a control panel to the right of the screen, with the tuner on top, and 5 or 6 smaller knobs in a row down from there. The later one has a large knob at the bottom right, for on-off-vol, if I recall, and there should be a Sams on the later one.

If your Colorcaster is the earlier 21" with the removeable side panel it has the 703 chassis.IT is in SAMS folder 305-11. Hoffman also produced a later 1957 21" color receiver which was basically an RCA CTC-5 clone. SAMS 385-3.

Where are you located? Helps to put that information in your profile, so we know if we can help you locally or not.

Hell Paso,TX. Not the greatest place but thats where the Army put me.

Should have mentioned it in my previous post. Is there a model/chassis # on the back of the set?
Could you post a photo of the set?

Thanks,
-Steve D.

Chuck,

Thanks to Bryan for kindly steering us to the Colorcaster photos. It is the later 21" 1957 receiver. Your's looks to be the "General" console in Mahogany model M4041. I believe it has the CTC-5 clone Super chassis. The SAMS 385-3 folder will let you know. The Hoffman Colorcaster "President" series for that model year used the CTC-5 Deluxe chassis.

Thanks for the info Steve. Upon closer inspection of the chassis,it looks like someone hacked some of the circuitry. I was told DO NOT plug the set in before it was checked out like I didn't know that already. I never plug a old set in without prior inspection.

Chuck,

While we refer to this chassis as an RCA CTC-5 clone, it's not a 100% clone. Hoffman did make some slight circuit mods in the chassis. Check the proper SAMS before starting restoration.

Steve, I am trying to get the SAMS for this set and you have a very nice vintage TV site. Let me ask you, In your opinion, I seen the sets on your site and all look new. Would you recommend me have the cabinets on both my sets re-finished or just leave them as they are. All the cuts,scrapes and gouges or actually restore them to new condition? I don't mind them showing a little age but these are beyond that. I plan on them being on display at our new house or in "My room" as my wife calls it. She said that all my stuff like the TV's and my old Majestic are all going in one room. Kind of like a "Chill room". She has no problem with all these sets taking up room in the apt. we have for now,She even loves my 1984 Sears set I got. Says it reminds her of her childhood because her dad had a Zenith set that looks like it.

Thanks for the help guys.

I'm glad you have the later chassis... The earlier one is a little more tricky than the CTC-5-ish one.

And Steve D, I'm curious now on the Sams 305... I don't have that folder, and I think I remember 25 years ago, discovering that the Hoffman in #305 was the other chassis (in addition to the CTC-5-ish one) that was different from the two sets I had from Gary H.... There was a fellow in Sherman Oaks who had two ColorCasters, with that chassis in the Sams 305. I want to be sure I get it straight on this. Gary Miller and I beat our heads in, trying to fix a problem in the horizontal on my mahogany one... All we had was the schematic pasted inside the panel.

I was thinking that the chassis in the early ColorCasters as mine, had a mutation of the prototype chassis as in the Hoffman 15GP22 & 19" CBS-tubed sets.

Hi Charles,

The SAMS 305 folder is for the 21" Colorcaster with the 703A-21 chassis. I assume this is the receiver with the removable side panel as seen in the article "Installing Hoffman Color Sets" included in "Color Television" 1957 Edition. That's the paper back issue published by Radio & Television News. You may have this book in your collection. Article on page 108. If you can, please PM your regular e-mail address to me.

Thanks,
-Steve D.

Hey Steve,

Right now the Packard Bell is on a back burner for now since it does currently work. (Just a crackle in the back by the HV cage and sometimes diagonal lines on a black screen.) The Hoffman is my main thing right now. I don't know alot about old electronics so what I thought would be smarter is since it is a "Rare" find, (I'm not sure how rare it truely is. Would be nice to know.) I am going to have someone who is a pro in doing these kinds of things restore the chassis. Most I'm doing now is simply cleaning up 50+ years of dust grime and dirt. All purpose cleaner, Q-tips,paper towels and an old rag got the chassis to a real close polish. But them old circuits, Especially them old wax/paper caps are a B#$%# to clean to read them. I'm cleaning this one now since I have the chassis out and getting ready for the "Hospital". I know for a fact, The cleaner the object your working on, The easier it is. And since I know the guy and the amount of work I'm about to give him, I want everything to be easier for him. This poor set had to be in a smokers house, The speaker wires are grimy and sticky, Actually, almost all the wires are like that. Where is a place to get a new grille cloth and knobs for this set? Removing them old knobs,one broke off and the others are badly discolored and look brittle. I've decided that I'm going to have the Hoffman cabinet re-finished so she can relive her glory days. I hate seeing her like this. Cabinet beat to hell, Chassis inop, supposedly a bad tube, List goes on....But I have the determination to get all my old toys as close to new as possible. Still haven't been able to see a SAMS photofact to see how to remove the tube. It has a plastic housing that covers it that is busted in many places.
