Silvertone 7140
Here's a Silvertone roundie I saved recently. Gotta be a rare one, I've never heard of it before. Chassis seems CTC-4ish to me, with the giant hockey puck doorknob cap and HV shorting plug. All original Silvertone brand tubes which test good, so it can't have had a lot of hours on it. Cabinet is beat to hell and back, gonna be another veneer job just like the CTC-7 Ed now owns. That means this one has to wait for at least a year while I catch up on house payments, all my money goes there till further notice. Unless of course someone has a 15GP22 to sell...

Here's the Sams on it, Steve was nice enough to put it up on the ETF site.

Reminds me a lot of a 19CT1 with that bezel.

That is one cool set. The metal shield over the front of the yoke, Looks like the ctc5 yoke. Is there a ground wire attached to it? What are you going to do with the grill cloth?

Yep, 528 is Warwick.

Is it missing an HV cage or did they just have all those tubes and the flyback out in the open?

How's the CRT?
That looks like a unique mount / insulator boot / edge magnet setup. |

Wow, what an unusual design. Definately not a direct clone of a CTC-4. I wonder if any more examples of that chassis still exist.

Yes, it uses a different color demodulation method, for one. Not to mention the different physical layout. And what's with that vertical centering control -- a dual pot with a 500-mfd non-polarized electrolytic. This set should make a very interesting restoration story.

It's missing, we searched the whole house looking for it but no luck. It's just a perforated steel box that covers the fly and horizontal related tubes, you can see it clearly in the full Sams. I only scanned the schematic info for ETF to upload, my computer can't handle large files for some reason. Probably time for an upgrade. Quote:
Wayne, the CRT tests very good but the base has seen better days. Probably going to have to load it up with sensor safe sillycone to shore it up, I'm too nervous to attempt surgury on a good AXP. The insulators around the tube are actually pretty close to what the Admiral Ambassador has, and I swear Anchor Co. had a monopoly on HV insulators back in the day- they made every single boot for every AXP set I have! lol Quote:

Right, I guess I just meant that it has the same doorknob and HV shorting plug so it has to have some borrowed parts at least.

The 1954-55 Motorola color sets had a vertical color chassis, but not really around the CRT.

Very interesting indeed! No PC boards either.
This will be fun to follow when you post the play by play.

The circuit is very similar to the licensee circuit Hoffman used. Should be a pretty decent performer when it's all buttoned up! Very nice set
