[QuadList] Amtec no output

[David Dean]

HI Ted and List

The list wins again !

Chris Hill sent through some diagrams last night and we now have a working unit. the only problem is keeping the unit centred, it drifts over a period of 15-20 mins, either one way or the other, this fault has been here all the time, and is not related to yesterdays fault. 

Thanks to Chris and Larry for their help

  Would having the dash number of David's Amtec be helpful, so schematics match the actual device?

    I am going to scan some diagrams for him.


    Since you are in England, the question is does this unit have the interswitch built in for 405 line operation?

      Hi List

      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.

      Thanks
