I may be posting this to the wrong NG, but there seems to be a lot of
knowledgeable people here, so maybe someone can help me. I have recently
acquired an old Revox B77 tape recorder which I want to experiment with.
Unfortunately, I have no manuals or other information and I can't determine
if the machine is a MkI or a MkII model. Does anyone know what the
differences are?

Lucky man!
I suggest that you ask the same question on the "Audio Asylum" discussion
group. Lot's of knowledgable geeks here!

Groups archive doesn't come up with much I'm afraid. My manual covers both
machines but irritatingly does not define the differences between the MkI &
MkII models. I'm trawling through the manual right now to find any & so far
the MkII has the addition of a tape tension pcb & tape move sensor
pcb. The capstan speed control schematic also differs slightly between the
two. There doesn't look to be ground breaking changes here..I think both the
MkI & II could have15ips as an option. Hey I'm not a Revox expert so no
flames pleeze.

Also, you'll find some manuals he

I've got the A77, 70 odd pages, about 2.5 mb zip in tif format. If that
means anything, or you think it's useful, email me and I'll send it to you.

Revox in general did not make huge changes between marks - they got it
pretty much right first time round. The 15ips option will certainly have
been an option from the start as the B77 succeeded the A77 and that has a
15ips option (I know because I have one). There is a yahoo group called
StuderRevox for owners like you and I and another group reeltoreel for more
general stuff but full of very knowlegdable people.

Many thanks everyone for your help and advice. I've discovered that my
machine is a B77 MkI (apparently, if it had been a MkII it would have been
marked as such) and I can now buy the correct spare parts and manuals with
confidence.
Cheers and best wishes to you all.
