Right now at the Elektron web shop you can buy the PSU-3c power supply. This exact model was included with my Syntakt. In Elektron web is said that this model can be used with all the Digi boxes (DT/DN/SY) and with A4 MKI and MKII. Months before, my Digitone and Digitakt came with the PSU-3b model, that has the same specs printed as PSU-3c. I guess I can use any of these 3 power supplies with any of my machines, Digi or Analog series.
On the other hand, the power supply that came with my A4 MKI is model PSU-3 and have different specs printed in the rear panel. My question is: Can I use the PSU-3 with my Digi boxes safely? Can it fry my small machines?
