As Keven mentioned, a lot of musical gear, especially Digitech effects pedals, use 9v AC power warts. They can be bought at most music stores and ordered online from places like "Musician's Friend" or "Sweetwater".

My local Guitar Center has a 9V AC power supply in stock and I was going totry to pick it up after work but I didn't have time.I did, however, take a look at the MC-10 schematic in the service manualand it looked to me that that with the rectifier circuit a DC power supplywould actually work (mostly) fine.  The service manual states the negativevoltage is only used for the RS-232 port.  So I took a minor gamble when Igot home and, sure enough, it boots up just fine on DC.  I'm not going tomess with the RS-232 port until I get a proper power supply but for generalusage I think the DC adapter is fine.On Wed, Apr 11, 2018 at 3:45 PM, rietveld rietveld <rietveldh at hotmail.com>wrote:> I use an old Nintendo power supply.
