Were there any CRT color portable tvs that had BTSC audio demodulating circuitry?

I've been looking at Sony portable and small tvs along with others and most only have a single speaker and the ones that seem to have two speakers seem to lack stereo.



I know even in the early 2000s a Sylvania branded 9 inch tv lacked stereo so even in 2002 a household television could lack stereo.

The few small TVs I've seen with stereo decoding had speakers on either side of the screen in order to give them at least a *tiny* bit of discernible separation - 20" being about the smallest I've seen with real stereo.

Since most people wanted small CRTs to make them fit a small area, a 20" TV with side speakers would take up as much room as a 23" TV, so they were never all that popular.

Now, regarding Sony, I can't recall a small CRT Sony with stereo. I do remember several RCA, Zenith, and Philips built TVs about 20" with actual stereo.

19" & 20" are the smallest I remember. Some smaller sets would do SAP.
Only small sets that may have had Stereo MTS would be TV -radio combos
but I dont remember any.
Zenith who patented MTS never built any under 20". Converters were
available. They ran off the tuner IF output.

Hi All. I was to modify my Sanyo TV boombox MTC50 with a MTS decoder from a old TV but never done it..


Probably the hold up was is to finding a decoder board small enough to fit into the cabinet..

The noise reduction system in BTSC (dbx) had a hefty patent license fee that would have been hard to justify in a low-cost portable.

I have a 13 inch Magnavox that is stereo. They also sold the same cabinet with the 2 speakers, but a mono chassis.

VK won't let me post pictures anymore. The model number is RS1355W101. There is one pictured on "the bay" right now. Mine says "manufactured June 1992".

In "the old days", someone could have used a "FRED II" or similar stereo-TV sound decoder with even a five-inch-CRT set, I would think. I had spare decoders already as of the mid-1990s or so, but no place in my house where I wanted/needed to set up a TV set to use one.
