Amp Problem SX PR902

Hello,

I recently got a Technics SX PR902 Digital Ensemble and was told the amp is not working. I don't have a service manual or schematics, so I am wanting to be sure that is the problem and then either repair the amp or replace it. I am more hoping that it is a repairable situation, because I can do that,. as long as I have the schematics...or means to narrow down the component on the board that is the problem.

If you can help, I would truly appreciate it. I use the piano for giving beginning lessons to psychologically disabled kids and adults and have the extra capabilities that the digital Ensemble has, I have found it to be more versatile.

If you can help, please let me know.

Thank you,

Steven
