Hi chet808,

as mentioned in the corresponding Owner's Manuals, the original power adapter models are:

• PSR-S910 (power consumption ?? W): Yamaha PA-300B
• PSR-S950 (power consumption 16 W): Yamaha PA-300C
• PSR-S970 (power consumption 20 W): Yamaha PA-300C
• PSR-S975 (power consumption 20 W): Yamaha PA-300C


The "C" model is the successor of the "B" model (and also the successor of the "PA-301" power adapter model).

To my knowledge, the specifications of these three models are identical:

Output Voltage: 16 V DC
Output Amperage (max.): 2,4 A
Output Wattage (max): 38 W


This means, you can use the PSR-S910 power adapter also for the S970 and vice versa. If you have to buy a NEW adapter, I recommend the PA-300C model:

Thank you very much just wanted to know because I have a brand new power supply that a friend gave me from a S910 now that I know it will work I’ll keep it for a spare just in case.

Hi chet808,

thanks for your feedback!

Yes, you can keep that S910 power adapter as a spare part für your S970.

As a precaution I recommend to compare the technical data which are printed on the adapters. It should be the values I mentioned above.

I would also test the adapter once on the S970 to make sure that it really works.


Best regards,
Chris
