Hi

Just joined the group as I've been given a 1990 vintage LC.

Unfortunately, it doesn't boot up and looks like a dead/faulty PSU.
The PSU, a TDK branded unit, just makes a quiet ticking ticking noise
and the measured voltages on the pins are way too low:

Orange wire: 0.6V
Yellow wire: 0.7V
Blue wire: -1.2V

(all voltages measured off-load)

I was thinking that I could rig up a PC PSU to supply the correct
+12/+5/-5V supplies but wasn't sure of the correct connections. I
presume that the Blue should be the -5V but which out of the orange/
yellow is the +12V and +5V? I see someone was asking something similar
a couple of years ago on this list but the question wasn't actually
answered as someone else could supply replacement PSUs. However, I'm
in the UK. Can anyone help?

Thanks

David
