Curtis Mathes 4224

I am needing help finding any info and a schematic for this tv. I did not find a chassis number, but there is a lot of dust and some corrosion. I am hoping someone recognizes the tv.

Here are some photos: https://photos.app.goo.gl/VWgJvQN8HxAZpdXH6

The CRT is not busted and the filament does have continuity. I am going to put the base back on soon and test the CRT.

Thank you!

You really need to find the model number or chassis number to work on this. You need a CRT tester to test the CRT because the chassis is probably not working well enough.
EDITED: Sorry I mis-read your post. I didn't find any Curtis Mathes 4224 at the SAM site.

I do have a CRT tester. That was my plan for testing the CRT. The model number on the TV tag is 4224, the issue is that the corrosion has covered/removed the chassis number. I was hoping to figure out which sams would have this tv if someone could recognize it.

First get some date codes off some ORIGINAL major parts.
Then find SAMS for similar models about 6 mo to a year later.
If you have access to a collection thats great. If not someone else
may or you may find them on the internet. You will find a similar
manual most the time.

If it is 62 or older I can pull folders and take pictures of the tube charts to help ID it...

It's badged as "Mathes" instead of Curtis Mathes so it's late 50's or early 60's.
They were built rather well then.

I figured it was late 50's. I did think it was odd that it was marked Mathes, but the tubes in it were Curtis Mathes tubes. I will attempt to find a date code tonight.

I really do appreciate all of the input and help so far!

The original Curtis Mathes tubes have date codes of 1959.

Sams Index says:
1959: Folder: 468 set 1
1959: Folder: 465 set 6

The model 4224 is probably a cabinet number difference.
Sams shows a 4200 series, folder 506.

I have ordered two different Sams.

The first sams covers chassis models: 1121, 2121, 3121A, 5521A
These models use a 21CBP4A picture tube. Which is what mine has.

The second Sams covers chassis models: 7323, 9323
These models use a 23CP4 picture tube.

Both of the photos on the front of the Sams shows only 5 knobs on the front whereas mine has 7, but I think these two Sams will get me started.
