Some remarks,
I copied the following from the site you linked to:
TECHNICAL SPECIFICATIONS:
Suitable for the following vestax mixers
Vmc004
Pmc05 pro vca (not standard version)
Pmc05 pro sl vca (not standard version)
Pmc06 pro vca (not standard version)
220 / 240 volt input
14 volt ac output
So, you need a power supply of 14 Volts AC!!!
I manipulated the photo to read on the label what current it needs to supply but the power supply on the photo is the 12 V model. So I could not find out.
A multivolt adapter is generally a DC supply!!!!
The connectors come with different sizes of the centerhole. Be aware of that. If the hole is too big then it looks like it fits but it doesn't.
