+1. If you want to be taken seriously in these forums you better post something a little more constructive..
Anyone come up with a BOM/cart yet so any dummy (i.e. me) can build/use the SSR boards?
If it matters, I plan on using a single PSU with a rectified voltage of ~50v

One module requires approximately 25 mA, so any small 2-5 VA transformer can do the job. I recommend regulated psu (LM78xx,LM317).
A short circuit can damage the mosfets in the SSR. (depending on the magnitude and duration of the current).
I want to warn everyone to use some current limiter and overcurrent detector in conjunction with SSR3.
The limiter current should be greater than the detector threshold current (which then activates the load/short disconnection).

Simple and cheap solution is a fuse.
Maplin had one in the output of their 225WRMS Disco amplifier.

Hi LKA what will be the case that my circuit having a periodically noise when connected to an amplifier.
This occurs to one channel only.
Swapping the boards the problem is still to the same protection board.
The other protection board works perfectly.
Noise is like an old t.v without a an antenna input.
It is audible even without music signal input.
