Is there any?It has to have a pcb to buy or a layout to make one my self.
I have +-69v DC that I´m going to use.Protection would be nice but not a must.Small size but all sugesstions are welcome.

Been loocking at some not DIY modules,is there any difference in sound quality in a fullbridge module that is designed to run on single supply vs. dualsupply?

Have a look at this modules: Connexelectronic
they can be powered from +-25V to +-72V and the output power is dependent on the supply voltage and the output stage components. the modules can be easy bridged, have on board BTL switch.

I can make a module with a scalable power of 500-1000W with possibility of inclusion of the bridge. If you are interested email me at contact@svpremvs.cc
