Thanks Douglas.,
I agree the soldering leaves much to be desired and will certainly consider calling upon the tutelage of others if available. I'm based in Manchester if any members happen to be based in my neck of the woods...
However, I'd be interested to know if there were any other issues you might be able to have picked up. Do you feel the problem might be purely the quality of the soldering, or do you have any additional feedback - parts incorrectly wired to another etc.?
