Hi!

My device has stopped turning on. I decided to fix the device. When I opened it, I discovered that the PCB is not like the boards of other devices that can be found on the Internet and in videos about disassembling the speaker. In addition, the PCB labeled "Stockwell" was not in the assembly at all.
Has anyone met devices with such PCB before? Is there a schematic diagram of the device or this board? What are these U11 and U12 chips on the board "JY-SPK-V7.0"?

My PCB:

Thanks!

I need to replace the footswitch, preferably with a heavy duty one. Do you have a soft copy of the owners manual and parts list that I can use? Or maybe direct me to where I can find one that matches the original.

This is one of my fav all time pedals that has always been part of my rig, and dont want to lose it.

thanks for your help!!

Tom.
