Hi there, 2 questions using my Seaward Apollo 500:

1- my radio connection between guitar and amplifier has a separate PSU, so is class 3? Should I simply PAT this as class 2?

2- my bass combo amp is a pretty new Ashdown Studio 15 which does not have any class marking (apart from RoHS CE) so has to be class 1? But this device fails earth continuity and I don't believe it is manufactured to earth the exposed metal parts. Can I ignore this test? If so, for what reason?

Thank you.

They should know what is in the box, if not ask for the internal schematic and we can tell you.
Either exposed metal should be earthed, or able to hold off a 500volt DC test to L and N shorted together with the mains switch in the on position. If it is not earthed, you verify it cannot come live instead.
