One point worth mentioning is that the RF1U has an RF Mains filter consisting of two 1.1µF RF chokes and four .001µF capacitors, as shown on the diagram in pic 3 of the first post above. Arguably as the four caps are all from Line to Earth they should be 'Y' Class. However, as they're disc ceramic rather than tubular paper I've left them in place, though some may take a different view.

I've highlighted the four caps in the pic below.
