10.5V DC power supply?

[Axtman]

I have an AKAI Riff-O-Matic pedal that I want to sell. The problem is that I can't find the original power supply and it uses 10.5 volts DC! Does anybody have an idea where I can buy cheap power supply? Yes I am checking my local Goodwill and thrift stores. I am hoping to find one for an old telephone answering machine (remember those?).

If you do a Google on 10.5 volts DC comes up with lots of universal power supplies. I'm thinking 10.5 volts is not a common output. Its usually 9 or 12 That I remember for most wall wort's.
