Ok that’s the network that has several legs on it I believe.
|
If that’s bad I Doubt I could locate that part it looks like it could be made up it’s all resistors.
|
If bad, it would have to be made up on a small pcb, It's been done before.

So this agc network would this be a cause for the voltage being pulled down via the 6hs8 tube ?
|
No, if not working the way it should, the AGC voltage/pulses would be all wrong, and tuning and IF would be all messed up and you would not be able to tune in anything.
|
Ok but when I get the tube I’ll try it but overall I still have the voltage dropping so if the tube don’t work out I’m still looking for a cause for the voltage dropping.

Could you sum up what is wrong with the TV NOW without going through the previous repairs. In other words plug it in & see what happens like you never seen the set before. I have lost track...... Prev screen shot looked good. But long distance troubleshooting is a challenge ! Many of us could take the TV like shown in the screen shot & vastly improve it in seconds. That would maybe weed out problems. Also remember NEVER trust a tube checker. The best checker is a known good NOS brand name tube. We had an advantage here. I could turn around & pull a tube from the shelf. It was abt 8' long & 5' high with sleeves of common tubes, more old numbers on shelves in the crapper. 73 Zeno:smoke: LFOD ! |

Got the 6hs8 no different but I did pull the 6cg7 AGC and vertical multi voltage stayed up I got a new 6cg7 made no difference so the one vertical half is working because I have a full screen so that may leave it to an AGC problem still bearly any sound scratchy static sound and with the 6cg7 in I can here a buzzing from somewhere. If k3 is bad or the cap inside is shorted I can make it up but it shows a line under the 94k resistor which is the .002 cap but it also shows a ground in the center of the line so where does the ground come from. I don’t remember seeing a cap with 3 legs. Does this mean 2 caps one on each side of the 94k resistor both to ground.
|
Does anyone know what this T line means 2 .002 caps one on each end of the 94k resistor

But the T does it represent 2 caps one on each side of the 94k
|
It intends to show .002 distributed across the resistor. When making a replacement put a .001 to ground on each end of the resistor so the total is .002
Is there another resistor that is covered by the black splotch? |
remove V1,V2,V3 ,V7,V8.
feed video back to test point B like you did before and see how long it can run like that. |
