Joe :
Modern units are smaller, and don't require ground isolation. (IF you can
completely isolate the ground, you don't need a converter at all, just an extra
fuse.)
JCW lists one that is a 1.25" cube, rated 50watts continuous at 12v.
Still a poor solution, IMO. Much better to convert to negative ground.
