Personally Fernando, I think that your LDR is faulty - going off your findings. That is just a 20 ohm swing.

Let me get round to it and I'll try and check the LDR in my CSY-1 that I am converting here. It should be the same. I do know LDR's are many and varied, so you will need the right one, but they are readily available.

You're in no particular rush for this?

Cheers,
TOM
