Both sides of the amp are working so its just a protection fault if that helps anyone to help me

It turned out to be a corroded pcb trak under the output protection relay. I would have been on ages without the schematic thanx again Tarzan for that.

No Thanks Cisco,

I had help from another contributor to this Forum.
It helped me to.

Glad to hear it whas a minor problem.
These are usually hard to find and without a ttrasure map (schematic) it can take ages...
Even if the amp is a simple cheap model or an expensive and complicated one.
A schematic can guide you through the jungle of pcb tracks, dangling wires and frightful electronic parts.

Oeps, my many years in the jungle is getting through...

Cheers,

Tarzan
