|The Sentinel is a 21-tube black and white television with a 16-inch CRT. The 16GP4 CRT used in this TV is notable for having a large bare metal conical shell that was directly connected to the high voltage supply and was mated to glass on both ends, so many CRTs like this tended to lose vacuum due to a leak at the seams between the glass and metal.|
I bought the TV at a VRPS swap meet in 2002 for 5 dollars. At the time, I was only in the radio collecting hobby for about 3 years and the TV was a far more complex repair project compared to most tube radios I had encountered. I spent 13 years on and off trying to repair the TV and making small progress each time. Read more on the restoration notes.
