Yow!  Test it on some scrap of wire first - if you pick the wrong
glue, the solvent will take the lacquer off the wire, and that would
be bad.  Superglue probably wouldn't, but who knows...

Speaking of 1084's, if I wanted to replace the COMP-CHROMA-RGB switch
with an electronic switch of some sort (I use my 1084 for watching
TV, and I'm worried about wearing out that big clunky mechanical
switch), what kind of switch do I need?  Something shielded?
Something with high power capacity?  Something guaranteed to
break-before-make contact?  A nice relay, a couple of FET's, or
what?
