oops . . . that could be a problem. After the
correct resistors are in place, measure the
voltage at pin 6 of the amplifier chips
should be about 9v. Voltage on pin 5 should
be about half that.

Thanks Bob, I'll check that and report back. It turns out the resistors were correct, but my EE friend thought at first that they weren't.
