Yamaha TRB 6P


Recommended Posts

I need some help with my Yamaha TRB 6P. I bought it about 14 years ago and I love it. It quit on me a few days ago. I'm not very technical  but I took the electronics cover off and found a small red wire had came loose. I can solder but I have no idea where to reattach it. Any help would be greatly appreciated! It's the red wire at the bottom of the photo.

I don't see a photo, but red is usually connected to the battery in active basses which would explain the bass being totally dead. Follow the wiring from the battery terminal, make sure that is connected to the PCB. From there, you should be able to follow the tracks in the PCB. Also, try emailing Yamaha to see if they have a schematic.
