Back by popular demand, the Deacy Amp Battery Simulator unit (DABS). This is a two-part unit. A global switch mode power supply capable of working on mains voltages from 90 - 250vAC and a battery simulation unit that the Deacy attaches to via its PP9 clips. The DABS unit also features a variable voltage output so you can adjust the voltage drive from 'brand new battery' all the way down to 'close to running out', which is just where Brian likes it!..
This power supply can be used with any Deacy style amplifier that requires 9V @ less than 1A.
