Anyone recognise this diagram?
 

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

http://jcgl.orpheusweb.co.uk/temp/Unknown.jpeg (about 3MB file)

Can anyone recogise this and say what it is?

Did Ferrograph ever use DIN connectors? Also can't say I can remember ever
seeing a 5 pin DIN used as a headphone socket. Sounds like something
Grundig would do. ;-)

I remember my Dad had a Grundig TK40 and that used 5 pin DINs for all
the connectors.

Well it clearly a reel to reel (probably) quarter track tape recorder
with built-in amplifers. However the type of diagram is quite specific
in that it has a component map at the top, and a quick bit of Googling
of diagrams of all of the well known German manufacturers suggests it
might be Uher.

DIN connectors were pretty common on most German stuff at one time.
Odd given the German reputation (and rightly so) for engineering things
well. Spawn of satan, DIN connectors. ;-)

Interesting. I've never seen a full size Uher machine - just their
portables.

An odd point of view, considering the alternative.
Who would design a plug that connects the signal before the ground?
And which leaves the signal pin so exposed when a cable is connected at one end only?
I'm sure that phono connectors have resulted in much needless destruction.

Ah! That may be an interesting clue. Thanks.

I don't recall ever seeing any Uher kit or diagrams. And - so far as I
recall - no Uher items in the anechoic chamber. However there could easily
have been some in the past which were discarded before I took over the
chamber.

The sheet has part of one corner torn off. I have been wondering if it
initially had one or more attached sheets which gave more info. e.g. What
we see looks like a tape-deck based system. But doesn't seem to have an
oscillator for bias/erasure. So maybe there were more diagrams and/or
sheets which actually identified the unit.

When they were associated with North East Audio Limited they produced some
cassette decks most of which had phono and din connections.

Obviously cannot see your picture, but just commenting about dins.

Lots of alternatives.

Who would design a plug that connects the signal before the ground?

Why would that matter? No domestic connector like that is designed to be
plugged and unplugged regularly. Unlike, say, a charger lead to your
phone. Or headphones.

And which leaves the signal pin so exposed when a cable is connected at
one end only? I'm sure that phono connectors have resulted in much
needless destruction.

Destruction of what?

Problem with the standard quality DIN sockets and leads found on domestic
equipment is they become unreliable long before a similar phono does.

You can buy good quality connectors to the same format as DIN, though.
