ctc12 clone beam current

Ok.... Dammit got excited for a minute....

Ok, So please check the voltage on pin 3, 6, 7, and 9 of 6KA8, V503A.

So Timmy, When you watch TV and the scene changes and goes from light to dark
and the picture blooms out, this is a problem you can easily replicate by turning
the AGC on a normal working tv.... Poorly adjusted AGC often make for a really
bad picture - especially makes them look like they have too much contrast, or
not enough.... It's possible, you have a AGC circuit problem here.... I have not
had that much experience in the AGC area.... Not sure entirely how the circuit
works, so outside of looking at known voltages I'll have to get out one of my
books and do some reading....

I was hoping for a bad ground, but there may be something funny going on
in AGC, and it's driving the 12by7a nuts too.... Gotta do some thinking...

Maybe someone with some smarts on this area has something to say....

So when you take the signal off this tv do you get snow....?

And is that AGC control mounted on the PC board, or metal chassis...?
