Recent Color Addition
Here's a picture of my newest color acquisition, it's a 1955 Philco TV-123. It's due to be delivered around the first week of December. Don't know if it works, but it is from the original owner and appears to have been kept in the main house all these years.
I've been back working on the 15" Philco prototype set and am now stumped with an AGC problem, not having any documentation or schematic it's been a real nightmare. The picture is washed out, it appears that the IF gain is down completely. There is no AGC control on this set to adjust, I have keying pulses but not enough video to turn on the AGC keying circuit. Maybe when I have the schematic traced and drawn out I can find the problem. Chuck
