Well I finally finished the TV. I added a Radio Shack 12.6v 1.2A transformer which powers the CRT alone. I put a two ohm 25 watt resistor in place of the CRT filament. I also added a 1.5 amp fuse in the main AC line for safety. I promised this TV to a friend, so when I delivered it I ended up buying a Sentinel 7" set in a wooden cabinet. Before I bought it I plugged the Sentinel CRT into the good working Teletone chassis to check the tube. It had an excellent picture so I told him I would take it! One more project! Thanks again for all the help. Al
