Ok, strange things but:

I replaced the 5V regulator for good measure but it does not get any decent voltage input nor would it then deliver the required 5V.

the 1.5ohm resistor at the transformer measures spot on.
The voltage at D3/D4 is about 28.8VDC and D6/D8 is about 6.1VDC which is a new development.

I also checked for injured tracks – all seem fine but I can’t work out why the 5V regulator isn’t getting enough ??
