The IC voltages look good with the possible exception of pin 4 of the 7660S which shouldn't be that negative; I'd expect about -4.5V. You may want to re-check that reading. But I don't think you have an IC problem.
You were correct. The pin 4 voltage is -3.7v.

Sounds like your signal is being (mostly) lost to ground. First thing I would check would be the wiring of the two I/O jacks and make sure you don't have one of the signal-carrying wires shorting against the inside of the metal enclosure. As I'm sure you know, there's not a lot of room in there!
Taking a closer look, I had the output signal wire attached to the 'ring' terminal. After relocating it to the 'tip', it boosts quite nicely!
Thanks again Bob for your most helpful insight!
