Power supply p?ug size/type - mkI module

[nocturnodrummer]

Hello guys
Does anybody know the plug size/type of an original 2box power adaptor? I don't have the unit with me at the time and have no way to measure it... I bought a spare one some time ago but the plug is different and want to resolder it. Any help is appreciated  cheers!

18 VAC output only and at least 500ma current supply. It can work on less voltage, I got a 3rd party one off eBay made by Alto, it was 15 volts AC/AC and it worked right up to when I sold it to a mate, who says it's still going strong!
