Does  anyone know of a current source for the 7-pin cable plugs that plug 
into 
a  7-pin miniature tube socket?  I found a successor to what looks like  
Amphenol's 8 and 11-pin octal style but no 7's.  



Here's how to make your own 7 or 9 pin miniature plugs: You will need some  
parrafin wax, a shallow container like a tuna can, a length of #20 tinned bare  
copper wire, some polyester resin, JB Weld or epoxy, and an old 7 or 9 pin  
tube with straight pins.
 
Clamp one end of the tinned wire in a vice, to a table or whatever. Grab  the 
other end with pliers and pull until the wire is straight with no kinks. Cut  
into straight pieces about 1" long. Melt the parrafin being careful, the 
fumes  and the liquid are flammable. A microwave is safe but tricky. Set the 
tube(s) in  the shallow container, and carefully pour in the parrafin wax until the 
wax is  about 1/4-3/8" above the point where the pins enter. Allow to cool, 
takes a  while. When cool, carefully pull the tube straight up. Insert the wire 
stubs  into the holes left by the tube pins. Mix up your glop, and pour it in 
the  cavity until it's just shy of the edge. Let it set. Carefully remove 
your plug  from the mold. If you wish, you can form loops in the end you will use 
to  connect your cable. Plastic chair leg covers, pharmacy bottles and some 
bottle  caps make good covers. Multiple plugs can be made with the wax mold 
until the  pins start to get loose. If you have a lot to make, consider using RTV 
or  bathtub caulk in place of the wax.
