[Boatanchors] Ideas for 7 pin and 9 pin miniature plug in modules

There are times when I would like to build a plug in substitute for a 7 or
9 pin miniature tube - for example, a solid state replacement for a 6x4

Back in the day, you could buy an empty plug in module from Vector or the
like.  Today those don't seem to be readily available other than in the
surplus market and even then I've only been able to find 9 pin versions.  I
have been vaguely thinking of generating a simple pc board layout and
having some made but, before I go too crazy, does anyone out there have any

FYI, for 8 pin octals, I just sacrifice an old tube - break off the glass
and use the old base. So octals are no problem.  And, of course, because
Murphy rules, I do have some old Vector plugins with octal plugs.  Go
