There were several models of the Television Analyst produced over the years.
I have a 1075 which is all tube technology, later ones contained more and more solid state circuits and were more capable of being used on solid state TVs. They also added more functions as time went by. I think the oldest was model 1000 and the last was 1077B.
Here is a article on the "Phil's Old Radios" website.

Also here is a link to a discussion on the "Antique Radio Forum" that is also linked to in the Phil's article.

You have to remember that old test equipment is made of the same things old radios and TVs are made of, the same power up caution is recommended.
