Sign of a bad speedo head or cable, rather than gear problems, IMO.

Most likely (unfortunately) the angle adapter died. Weakest link and all
that.

Could well be. The Stag I bought last year had exactly this problem. He
had just replaced the cable & angle adapter, but it was really the speedo
head that was bad. After driving for a bit, the dry bushing inside the head
got hot and bound even more, causing the angle adapter to break. Problem
was obvious once I got the speedo head out, since spinning it by hand showed
it was much stiffer than it should be.
Also check that your inner speedo cable doesn't protrude too far on the head
end. I've heard stories of them being too long and putting pressure on the
movement, with similar results.
BTW, your speedo will probably still be inaccurate after you get it all back
together. There is another drive gear inside the J-type that I believe is
different between the Volvo & TR6. Unfortunately you have to disassemble
the annulus housing to get to it; so it's probably easier to buy a ratio
adapter to go in the cable between OD & speedo head. A local shop quoted me
$100 a few years back (including the new section of cable between box &
speedo), but it's probably more now.
