I've been working though a folder of old Ferrograph documents, scanning
them to put onto the ukhhsoc website. I came across a circuit diagram that
doesn't look to me like it is of any Ferrograph item. Presumably mis-filed
at some ancient time.

I have put a copy at

Can anyone recogise this and say what it is?

Jim
