Sencore CR70 crt tester Demo tape
 

Over of FB vintage tv forum, a person "who was bidding on one on ebay" asked the seller to upload a copy of a video tape included with the tester, well he did and it is on youtube. This tape is a usage guide/ promotional advertisement.Tape was made in 1983 with words from the president of Sencore, how to use it and even some pics of the Sencore headquarters. Kinda neat! here is a link

That's awesome! Thanks for sharing the link :)

This was interesting and very informative.

I also loved the shade thrown at B&K and Beltron. :)
