Hi bitbot
welcome

The psychoLFO and most synth modules need a power supply that puts out +15V, -15V and 0V (or +/-12V if you prefer)

Most power supplies you see in the shops only give 0V and +15V, or wallwarts are usually 0V and +9V

Your cheapest option is to get the CGS 14 PCB, if you don't want to do wiring to mains, there are ways to run it off an AC wallwart.

Have a google around for 'bipolar power supply' to see some projects and get an idea of what you need.
feel free to ask any questions here too.

Just an FYI, I was running the Psycho LFO @ +/-9V without any noticeable issues..
