UTC Transformer type H-89

Upon the date 12:18 AM 10/28/01 -0400, Glen Goodwin said something like: Without digging through several boxes up in the library for my 1950's/60's UTC Company catalogs, I will say this is for an early 50's television - a large screen black & white or one of the early color sets. I could check if you'd like me to. I feel it is obvious this is the case based on my considerable experience with early TV's. My assumptions on the secondary lineup is as follows: 5V @ 6A for two 5U4G full wave rectifiers; 6.3V @ 4A for the damper tube heater and the CRT heater (meant to be isolated and held at a higher positive level to prevent heater-to-cathode breakdown because the cathodes would be at maybe +250 volts DC or so), 6.3V @ 8A for the rest of the tube heaters, 850V @ 430MA, 1050V @ 400 MA. for the B+ voltages. Methinks the two high voltage secondaries are a single center tapped winding with a choice of two tapped levels - depending upon the original requirements. This is apparently a replacement transformer meant to fit several different chassis. Well, if I had, for example, a 1954 RCA color TV with a bad power transformer and this was a replacement, I think I would fork over that much. Probably not more, but maybe that much. In this example I gave, the RCA CTC-1 chassis was the first color set mass produced in the States in 1954 and this USD103.50 would be worth it to me if I knew I could get a working set.
