CP-70 Power supply
« on: September 11, 2018, 04:38:02 PM »
Hey guys. Im looking to modify a power supply to fit my CP-70. I have the coveted cp-70 2 pin xlr, the cable is just shot. Im on too tight of a budget to pay $75 for someone to have made one that I could have done myself.

You want to buy a 18v DC power adaptor with enough current to power the piano.

The CP70b only takes 40ma so go with something higher than that. All the aftermarket supplies I see online use 500ma - 600ma so they provide more than enough power.

I'd use one like this:

Mean Well, 15W Plug In Power Supply 18V dc, 830mA Level VI 1 Output, P1J Switched Mode Power Supply

The bonus of this supply is that it accepts voltage from 90v - 260v so can be used internationally without any problems. It outputs 830ma so more than enough for the Yamaha.

The only problem I have with these aftermarket supplies is that the cables are very thin and can be easily damaged. The original supplies had a 5 or 6mm cable to protect them when they were on tour.
