a real challange?

I have a Stromberg Carlson TV-10 which is their TV-12* with a just a wood shim added to the mounting to accommodate the smaller CRT.

If you can figure out which RCA it best matches getting a new IF can should be fairly easy.
RCA successfully licensed the '630' chassis from 1946 to 1960 (as time went on licensees piled on mods to add AGC and large screen CRT support).

Cabinet wise you could probably use an RCA cabinet or any clone cabinet if you're not set on the exact FADA cabinet. The first two RCA sets the 630TS and 8TS30 used IIRC a wider knob layout than the later ones like the 8T241 and 9T246. Heck you could even build a custom cabinet as homage to the configuration you remember.

If you can't find a 12" cabinet you like you could get a 10" CRT and swap to it....lots of options.

If I do ever attempt to work on it, it will be after I pull the CTC-90 out of storage next year and start to bring that up. I doubt I'll ever find a tube / hybrid set to stick the 25vxxx22 into, & I don't just wanna leave it out for ever getting dust on it, so I might as well have it in a working set in the meantime, and perhaps something may show up later.

I have pretty much done all I can with the CTC-16XL , aside from the IF alignment issues, & the slightly annoying retrace lines that pop up 6% of the time, (most likely will never understand why.)
Now sitting in it's permanent location and used every week or so.
