I am happy to supply bare pcb's if anyone is interested.
I will include microcontroller already programmed.
£4-99 plus £3-95 p+ if uk else £11-99 p+p rest of world.
£5-99 for DC protect, over current detect and power up/down detect pcb.
plus £3-95 p+ if uk else £11-99 p+p rest of world.

Three generations of speaker protect circuit.
1st is mechanical relay with dc detect.
2nd is solid state relay with dc detect.
3rd is solid state relay with dc detect, over current detect and power up/down detect.

Built up a couple of the all singing all dancing speaker/amplifier protect modules.
I have left out the mains transformers so if you use a different mains to the UK you can add your own local mains transformer.
£14-99 plus postage costs.

I can add mains UK transformers for £4-99 extra per pcb.
I still have some pcb's left.
Simple DC protect and power up delay with and without uk mains transformers.
