Hello Seth -- regarding the rusted transformer, I have found over the years
that "Hoppe's Gun Powder Solvent", of all things, with Q-tips works very
well for such items -- Hoppe's is a mixture, so I have been told, of
bananna oil, kerosine, and ammonia. The ammonia works as a solvent while
the bananna oil and kerosine also clean but leave behind a light oil that
keeps further rust from forming. You can find the stuff at any respectable
dealer that sells target shooting gear and the like.
Also -- you can bask in the gentle radiated odor of ammonia, bananna oil,
and kerosine as your favorite computer warms up -- it actually is kind of
nice.
Regards
Jack
BTW -- see
http://www.bs2000.com/talos/vintage.htm for a photograph of my
ancient vacuum tube radio gear that I have restored over the years -- when
powered up, close to 100 vacuum tubes come alive -- all smelling of
ammonia, bananna oil, and kerosine -- ahhh the glory of it all... :)
