Stromberg Carlson X-21 M4B project.
 

This weekend I intend to go out and get that Stromberg Carlson X-21 M4B television that is to be my restoration project next year.

It's a bit of a drive, but not TOO FAR, but I am having to borrow my mom's car to move it, ( laid face down in the back on foam and covered with blankets ) as there is no way to fit it in my Yaris. :(

I can find little about this specific model “M4B” but it IS seen in this reference, http://www.earlytelevision.org/pdf/rider-67.pdf
And I know that the inner core of it, X-21 was used in many other sets, so it should not be that hard to deal with.

From what I saw, the cabinet had some exposure damage, and will need some work as well, no telling what the chassis is like after being in storage, just gotta wait ant see! :)

But the very first thing I will do when I get it home is get the 21AUP4A on my BK Precision 490B, and see how well it is going to wake up!

Since you're not in a hurry keep your eyes open for a copy of Riders Television 16. There is a PDF available but I hear they were scanned in black and white instead of greyscale. Those higher volumes should be between dirt cheap and free if you can locate one.

i have it!

losing some DAG already :(

Just knock the loose stuff off, mask the areas that shouldn't have dag and spray some Slip Plate on it. That will fix the bald spots long term.

The chassis is in better shape than I thought it would be, having spent unknown years in what appears to be a barn or something, it IS still quite dirty topside, I may try to clean it off before setting it aside for the cooler time of year to start on it.

The cabinet will no doubt prove harder than the electronics itself, having taken most of the beating over the years, the wood under the chassis has to be replaced, its ruined, and I will most likely pant the entire thing after removing the rotted bits and filling it in with filler, its mostly all on one lower side.

One thing that may be a PITA once I get this thing working and cleaned up and ready to go back together, 2 of the 3 little control knobs on the front are missing, not gonna be easy to find 2 to match the one left or 3 that fit that look well on the set. :/

You guys are really cooking down there. My son is southeast of Austin and reported 99 over the weekend. With the humidity I think I would wilt doing anything outside during the daytime. :sigh:

...

yes, we be roasting here :(

Well you all could come to Wisconsin to cool off in the severe thunderstorms we've been getting the last couple of days... The dime sized rain drops are refreshing till the thunder scares you inside. I make it sound so appealing don't I? :D
