Seems like the fault, well documented and thanks for the link

"Of all the PSUs I've ever repaired I attribute 90% of them to a dead
chopping transistor (the vertically mounted one in TO3 case).A BU208A
is a suitable replacement.

The way to tell if it's this is to unplug all the power leads from the
motherboard and switch on - you should see 5v as usual.With the power
leads reconnected you'll struggle to get 2v out of it."

I searched google for hours before posting and couldn't find this reference.

Thanks again.

I'll let you know in a follow-up shortly.

Regards

Andrew
