The 7815 needs only 3 volts of headroom, so 23 volts is plenty. Any more
than that will be dissapated as heat. Your right that the traces will also
get warm but it's still safe. The other post that advised the use of
freeze
spray was a good one too. I have used both...Eddie

See my previous post about finding the culprit but I had another problem
and
it was the 7815 3 term reg which I replaced with NOS and the Wavetek
came
to
life but not great. I measured the 15 volt terminal and it was 23 volts
so
I may not have much left. I have question on your method. For a
shorted

I think he was referring to a 15 volt rgeulator that has 23 volts on the
output indicating it was bad and the overvoltage caused other components to
go bad.
