Hi Punkfolkrocker.

A little story first!

A couple of years ago I had to take a wrongly delivered letter round
to another company, I walked into their office and stopped inside the
door to get my bearings. Straight away I noticed the smell, rancid
fish!! I said to the receptionist "you have something elecrical
burning in here, check your sockets and things". They had two heaters
running and when she touched the plug of the second one she burnt
her hand.

Please check the electrical things that you have, that smell is
characteristic when some of the plastics that they use are getting
hot.

Best wishes
