Well now after getting a decent picture with direct video injection, I can't get a good picture through the antenna terminals.
So I replaced the resistors in the IF stages. The caps were previously replaced. Still not a good picture. I get decent sound though.
So I tried a quick alignment but the signal was very small going through to my VTVM. When I made an adjustment the needle moved just a little bit.
After that I tried it again. No joy. Here is the picture I get of a test pattern. You can see it is there, it just isn't very good. The tubes were tested and they are good.
Any ideas? Thanks.
