Hi Paula
Thanks again for your advice. So the problem could be the low output in power from the hw16. I see 115v transformers on ebay rated at 200w going quite cheap, mainly for powering other low voltage equipment. Would one of those be suitable for the hw16?
Another thing that puzzles me is I have traced the 108v from R11 to pin 1 and pin 5 of V2 to pin 3 of V2 despite having passed through R1 which, I assume, should drop the v to the specified 90v. I have checked R1 in situ and it reads the 10kR that it should be. So why is it not dropping the voltage?
Sorry to be such a pain, but as you will have gathered by now my electronic knowledge is very limited!
