This is the LILT power supply ISP12. In addition to 12 fully isolated outputs, you can choose from a variety of voltages and currents. 5 x 9V (150mA) 1 x 9V (350mA) 2 x 9V (500mA) 2 x 9V/12V (350mA) 1 x 9V/18V (150mA) 1 x 4V~15V (150mA) SAG *All center negative Personally, I was very grateful that the main unit has a master power switch. When using the board at home, it was troublesome to plug and unplug the power cord every time, but this power supply has a master power switch, so it was very convenient to turn it ON/OFF on the board. This is an auction for the main unit and the dedicated power cable only. Please note that the DC cables for connecting to the effects pedals are not included. There are some traces of Velcro on the back of the enclosure. Operation has been confirmed. No price reduction is possible. Thank you.
