picture looks a bit washed out. Did you try adjusting your AGC control? If you did and it didnt help darken up the picture, test your IF tubes and that 6HS8 AGC/clipper. Should that not be the case, then check your video amplifier tubes. you should have probably 25KV on the the anode if HV is properly set. To check the HV, turn the brightness and contrast all the way down, then try to stick the HV probe between the anode cap and the CRT well and adjust your HV for about 25 KV. Your focus voltage should read at 5KV. Poor/ corroded connection to the pin of the crt can cause the focus to go off. But if you want, touch your HV probe on the focus lead (probably black) and see if youve got 5KV, if so its a connection problem most likely.


Just as a safe rule I follow, when I get a TV for the first time that I work on, I test every tube in the set, even though the set might appear to work ok. Sometimes the set is working good but the grid leakage is poor, or a life test on a tube fails indicating trouble is on the way. Its just a good habit to get into I think, it also makes you feel good as you now know ALL the tubes are good, and you feel more confident in relying on the TV to work good.

keep us posted.
