Vintage Synth Repair

Class 2 only means that there is no earth connection from the power socket
to the equipment.  My experience says use any ac adaptor that gives the same
output or better mA, for example provided the output is 9V DC you could
safely use a 2A unit or even higher, what it mustn't be is lower in mA.  

 

Note that an adaptor may not say specifically that it is class 2 but if it
has two concentric squares, i.e. one square inside another, it is class 2
this symbol designates it so.
