Don't have an oscillator, was hoping someone had come across a similar
fault. I know the PSU's can cause problems in these models, just wondered
if
they caused this fault.

You can knock together a 2 transistor squawker that's help but you'll need a
manual really unless you're experienced. Check the voltages on the
transistors for sure.
