When I get a few minutes I'll compare your circuit with my module. Although I used mine with an output decoupler, I was wondering if the module was originally designed for split supply working. I think there is a 0V, +V and -V marked on the board but they are hard to make out. I have a link soldered across 0V and -V on mine. I remember a resistor burning out at one time and I had to guess what the value was. Don't remember how it happened, I think I was about 15 at the time.
