u/19-24

Hi, i have got this PCB of a Prophet 5 Rev 4.1 from 2019/2020 and only have the Extension Board with the other 5 Voices. So it should be the Prophet-10. Can i Just use a Laboratory Power Supply with the right Voltages to start powering it? I'll prob. Need 2 for connecting the 6 Pins. I know there is a Control Panel which i dont have. I plan to Hook IT Up to Power, Midi and Audio Out to Check If it works. Do i need to Ground the PCB anyhow? Normaly IT sits inside a Metal Case. Glad for Input!
