Thanks for the prompt replies. I'll check out Maplin tonight.
As for the bell spec, I'm not sure how to answer that. Its a doorbell - goes DING DONG. I bought it because I could hear it and it was LOUD unlike the stuff I had seen here. I had already tried wireless and they just dont work...
I bought a door bell in the usa and now I want to install it here. It calls for a transformer described as follows
Low Voltage Transformers, Input: 120VAC, Output: 16VAC-15VA
Any suggestions where I can get the equivalent for UK input. I wondered about the lower level of recessed lighting...
