Hi Dazzlevision, yes, I did check the focus slider, it has gone a bit low, measuring a little over 2 meg, I will change it though, I will have to see if I have a suitable replacement.
I will run the set over the weekend to see if any faults come to light, but so far it is behaving itself, not bad for a set that has not seen a picture for nearly 30 years!
I have a Pam 600F on the to do list, but i bet that will need more than 3 caps replaced....
