tv alignment equipment

[Tony F]

Hi guys, I plan on visiting a gentleman to pick up some tv alignment equipment. I know he has a B&K 1077 but I'm not sure what he has for sweep/marker stuff. Is the B&K 415 able to do the late 40"s early 50"s with the 21 Mhz I.F. ? (Do I have that right ?) I know he doesn't have any Sencore stuff. What should I look for that is capable of doing the early sets. I know they switched to a higher frequency a few years later. He might have a few different Brands and models. What can you recommend ? I'm not sure how much late model tv stuff I plan on getting into.
Thanks
Tony
