Musician questions

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.

    Not something I have experience of, though I have PAT testers and the C&G qualification.

    There doesn’t appear to be any helpful information online, I suspect the amp is Class I without any exposed conductive parts on the case other than possibly the input and output connection plugs.

    A question to ask the manufacturer for guidance on. You could possibly unscrew the mains inlet  IEC panel connector to see if the earth is connected, but then you could confuse the issue if it has fell off ?

    I was typing that while you were posting your last post, so have not taken that into consideration.
