[ARC5] Powering and RAX Sans Dynamotor

[David Stinson]

Since finding two more dynamotors for the RAXes 
looks doubtful, I decided to build another DC/DC
supply into one of these rare, exotic and terribly
expensive project boxes.

90 VDC runs the rigs fine with plenty of audio.
This particular DC/DC converter is wicked for
noise,
so I probably over-did the filtering in and out of
the box, but I had the stuff and it worked well.

A dollup of mighty Shoe Goo mounts the doohickey.

One banana plug for ground and "Locator pin,"
then soldered some SolderWick braid to the two 
feedthru caps and cased with heat-shrink to
make "brush contacts" that insert in the
A+ and B+ connector holes.

On with the top and the noise goes bye-bye.

I'll solder it closed later today.

Need to build one more.  Will try it with
a little less ferrite and see if it still
works OK.
(P.S. The tea was good, too.)
