what is the output on this adapter? (volts and amps)

According to the description: 9V, center negative, 2A (2000 millamps) max. 18 watts. (9v x 2a = 18w) The other answers here are wrong if the product description is correct (and they don't even agree). The original PSB-1U had the specs I just listed.

What is the cable length? Thanks in advance.

from the outlet plug to the transformer box is approx 3 feet from the transformer box to the outlet on my keyboard is about 6 feet with an overall length of 9 feet

there is no place on my FR7 that would accommodate that adapter plug. Please help

The FR-7 is powered by the foot pedal that comes with it - this attaches to the FR-7 using the included 19-pin cable. You can also use the battery pack for powering the FR-7, and this is charged using the foot pedal also.

Will it work with HP 137 R?

I am sorry, I really do not know it it would work or not
