Anyone out there know the specs. for the power supply (wall wart) for the Yamaha QY-300? The manual does not list the specs. and the machine says only "DC in" with no specs for the Yamaha PA-1207 power adaptor. I lost the original one during a long period of not using the machine, and will order another, but meanwhile would like to use the machine using a "one size fits all" power supply. Need voltage, polarity and capacity in m.amps.

Have you tried to eMail Yamaha? I´m pretty sure they have the specs you need

The CBXK-1 XG uses the PA-1207, PA-3B or an equivalent AC power adaptor.
(according to Yamaha's manual)

I've got two PA-3B's for my AN1x and QY100.
specs: 12V 700mA inside=+,outside=-

polarity and voltage should be the same, not sure about the 700mA, but on the other hand they might have 'hidden' the specs in the name '1207'

Yes the specs are the same as the PA3, and hidden in the name. 12V 700mA. I wish we still did this, it was so easy to know the power supply specs. But as we change vendors, we have to rename the power supply. I guess PA1207IV sounds kind of silly for a power supply, huh?
