Hi Sparky,
Thanks, will check postings as have had several 17IPS-whatnots in for mending recently and have discovered three different types - all of which seem to have invertor probs. Meant to say one transfomer or two rather than sockets.
Got a new S02 from a revered Northern Quuq'er, now with external underpants - will try it and report - Chris.
PS - S02 did the biz and the pound made - Feet up and pouring - Chris.
