I'll have to check and see if it's got AGC. I'm not too sure right now.
Well, I adjusted the fine tuning some and got it set up pretty good. I just turned a few screw's like the schematic said, to "tune it up". These were the one's around the tuner and fine tuning knobs, so before anyone starts screamin' at me, I did not mess any with the alignment!...yet. It's still got the snow issue, but all sound has been fixed with the above chages. I also tested the tubes on that tuner and they are good! For some reason, the set is back to going to a dot when you shut it off. How do I eliminate this? I don't want an Ion burn in the future. |

Been a long time since I looked into this set. Still really want to get it straightened out.
I finally got to looking at the schematic again and after studying it, I found the AGC....but there is no control to it. It's fixed...in that it is operated by some odd device that has 4 or 5 leads sticking out of it. On the schematic it is listed as K5 on pg4. actual picture of the thing is on pg7 http://www.earlytelevision.org/pdf/R...Sams-396-3.pdf Any other idea's to fixing my snow, with a strong signal being imputed in by standard coaxle cable and adapter? |

anything? I don't know what else to do about/with this set now.

Snow like that is often caused by weak tubes in the tuner. I would try substituting both of them with new old stock to see if it clears up.

If the metal shield on the bottom of the PC board isn't put back on correctly with all the ground points connected to their spot on the foil it can cause interference in the picture.
Did you clean the area around the anode connection on the CRT? The vertical on these sets is always touchy, often caused by a resistor out of spec or one that drifts when it gets warm. |
