troubleshooting voice modulator Answered
About four years ago I bought this robot voice kit for a halloween costume:
(the scematics are near the bottom of the data sheet)
I never finished it and now that I put it together it's not working.
The signal goes through to the amplifier, but without the modulating happening.
Does anyone know what the problem could be, or if there is a way to narrow it down without desoldering and testing the components individually?
