Re: Ferranti 355 radiogram. PAT Test advice needed.
I agree with Duncan. This is a hopeless quest. If you have an unsympathetic PAT tester who doesn't understand the issues and context, then you will never get this approved. You may as well rip out the guts and fit a 99p Chinese class D output module powered by a wall wart. Nobody here will be very happy about that, but the care home residents are unlikely to be bothered.
