I did think it was strange that they didn't label the functions of each photocell on the front. I guess you were just supposed to memorize it. I did power it up. It has promise. The raster came up & it just has the typical vertical problems, short with foldover. The remote motor works fine with the manual switches but none of the "eyes" are responding. The bad news is the crt is pretty well shot. It had a brightener on it; I hooked it up to the tester & the needle didn't even move. I ran the filaments all night at 8 volts but it never budged from about 1/4 through the "bad" scale. So now I can look for a 21ALP4A or equivalent. I looked up all the substitutes-will have to check on the ETF classifieds & see if the poster on there has something. I have some other 21" tubes but they are not on the list, I think maybe I could make one of them work but for now I won't worry about it.
