[ARC5] DC11 or DC11AA crystal holder dimensions?

[Tim]

Hi Tom - yes, that was a surprise....(I have a very good dial indicator
that I trust).  I have not disassembled this crystal but I note that the
pins have hex "nuts" at their base implying they are threaded into the
bakelite case from the outside.  So there may be room for some "slop";
bakelite machining being somewhat non-precise.  I don't know what the pin
spacing tolerance spec may be.
I only have this 1 crystal so my sampling statistics are pretty poor!  But
I am sure a "3/4" socket will be the way to go.  BTW this crystal fits
nicely in the "big" crystal sockets on the GRC-109/RS-1 transmitters too.
(Why?)  haha
