Default Re: Eddystone 840A deafness.

When was it that the "X" and "Y" capacitor designations started to be used? I've seen some pretty ancient capacitors with these markings on them over the years. I suppose that this particular case in what we would now call a "Y" requirement failed in the desired manner though. As far as I can make out, the 670/840 series appear to have been derived from the 710/740-series type receivers but with a goodly sprinkling of insulating washers, bushes, strips and couplings to isolate case from chassis- quite impressive as a diligent adaptation of existing hardware for the contemporary requirement of a DC mains-capable cabin receiver, but I wonder if they would get away with it today in a "general sale" context.

Very true, a sad sign of the times! There's still a few nuggets out there though.
