V659 is the smaller (7 pin) tube socket below V634. Both it and V634 are
under the components straddling the ceramic strips, so they are harder to
see and probe than V620.

But where on the picture is V659?

Can you send a picture that has that area about twice as big? Or send a
higher res photo directly to my mail?
