Graydog7

I got one like this too, for £10 from a nice local chap on Ebay. Apparently the batteries inside the Hygro/Temp/Transmitter unit run down in about a month. I've had a look and it seems the blue trimming capacitor on the circuit board has blown. Replacements are cheap, varied and plentiful but as it has no identifying marks on it and I can't find a circuit diagram I'm not sure which one to get, for now I've taken a different looking one out of an old temp/hygro unit and It seems to be working OK but if there is anyone here that has any info on the electronic components of the N96GY I would be very grateful.
