<P> </P>
<P> </P>
<P>Go to Amtec board #4, put a meter on the two test points: check for +12vdc and -12vdc.</P>
<P> </P>
<P>If its there, board 11 or 12 or the delay line may be at fault. 11 gets the line video in before the delay line, 12 puts the video out after the delay line.</P>
<P> </P>
<P>All the other Amtec boards dont come into use until tape is being played back and the switch is in one of the correction modes(would be ext. ref. for intersync)<BR></P>
<P>OK, hope this helps some,</P>

<DIV> </DIV>
<DIV><FONT size=2 face=Arial>My Amtec has died giving no output, I am very lost as I have no circuits for the unit, I do know video is getting to the delay, and getting through it but that is about all. Any good test points? a block diagram, or circuits would be a help.</FONT></DIV>
