Thanks for that i will put it in my note pad and keep a page in the meter cover. Graham its done . The pot was as we said faulty . Volume working as it should now . Last night i did a postmortem operation on the old pot . And i can see a part of the carbon track that was very shiny .And only one 1/4 of it had carbon showing i think this was the place it was doing nothing .I did take pictures but its hard to see the track .So Graham this is another post you can put to bed for now . My next job is to recap the Trio no1 .
