    Shek, Thanks guys, It seems we are all focussing in the same area so may be that is it. I have 2 alternative psu to try this next day. But if anyone can point me in the right direction for tech info or circuit diag I will be happy. many thanks shek

    shek replies Thanks Squify, thanks Scorpion. I can confirm that it is a Multiplexer (16 way) AVC 706- ancient I know, but it used to behave better. I am keen to get the soldering iron to it but, without manual or any literature or circ diagram, I might spend more time on it than it deserves. but I will be looking at any shorts on the external psu side first. After 2 days as a member I am impressed and greatfull for the response. All ideas are welcome. thanks Shek

    This one is for the veterans... subject: AVITECH AVC 706 multiplexer, I would be greatful if anyone can tell me, why the MPX powers up and shuts down when it wants to. A high pitch audio tone sounds continually and all indicator lights remain off. switching off and on restores the machine, only to watch it do the same again. shek.
