Help with Mullard E7600 Valve Tester

[mendipviews]

Thanks for links Yorkie, indeed they have helped a lot with information and circuit diagrams for the tester.
I opened the boxes I got with the tester last night and indeed theres a lot of cards in there but didn't have time to look right through them.
As Steve P says there are some test cards in there and I will have a read of the manuals as to there use.
First job is to look at the components this weekend.

Many Thanks
Luke
