"I just spoke with Eimac and they are going to research the SK-800A socket.
It has a 1964 date code"
Bob,
I just looked into a 1961 Federated Electronics counter catalog and there is
an SK-800A listed. The Air System Socket is shown for the 4CX1000A and the
4CW2000A. It also shows a 1500 mmfd screen bypass cap, again with 'no
terminals grounded'.
Since the 4CX1500B has a slightly higher filament current than the 1000,
perhaps the 'B' socket is a little more robust?
