Doug, it never ceases to amaze me how you can find room for all the TVs you collect.
I've said this before in another thread: Your basement must be huge, or else you have storage sheds on your property.
BTW, I had a Zenith J121Y b&w 12" solid-state portable TV which was made in Mexico (that's what the sticker on the back said). I don't know just what part of that country the TV was manufactured in, or for that matter how many manufacturing plants Zenith had in Mexico in the late '70s; perhaps the one in Reynosa was the only one they owned.
That Zenith portable was probably the best b&w TV I ever owned in my life, as it lasted 22 years and was still going strong, bright CRT and all, when I got rid of it after moving to my apartment in late 1999. Only thing wrong with it was a broken UHF tuner detent mechanism. Perhaps someone else in the building spotted it near the trash barrels in back and got a few more years of use out of it; heaven knows I got a lot of enjoyment from it.
