Yamaha Analog delay pedal power supply.

[dyn]

Hi. I have a delay pedal like this: Vintage Yamaha Analog Delay AD-10 Effects Pedal - YouTube. But no power supply. How can I get this thing going?
(I don't have the module system it was designed for, but it does take a 22v adaptor as a stand alone...
Help! Can I get something made up in uk?
