It was the use of Tunstall in front of 2500 that was confusing me. I, wrongly assumed that who ever started with the Tunstall 2500 knew something I didn't.

And yes, I know all you have mentioned and volumes more.

Didn't you know me old fruit that it's better known now as "menvier" :)

Coopers got them all if you need to work on the ts tunstall range or the cpa range,pre munford & White.

Maybe we all should take a trip down memory lane (pre munford & White ) lol.

Where do you think scanny got their concept in design for the 9500 from?, think cpa6,anyway me shut up now and happy reading it's a good panel :).
