Well it came in the post and sure enough it works. But seems to be slight signal 'filtering' on channelB and the cal signal is warped badly so pull apart time (and check caps). Ill post pics of the inards if I notice any differences.

Thanks for the blogg.
I got one at a computer auction, I don't think most of the punters knew what it was. I couldn't see it working, so I bid on it for the case value to me.
It was with  a lot of computers from Reuters and I don't think was used. The brightness control shaft was slightly loose and you could only turn the control down and it slipped when it was wound up. Easy fixed.   No dirt dust scratches. That was at least 15 years ago and because of its size, it is my bench scope of choice until I need the features of the Tektronix units (rarely)   I'm about to check if I can brighten up the trace.
Thanks again for all the info.
 :)

Welcome to the forum.

If you check the manual linked (and it's not quite right for my units) on P39/41, VR10 is listed as Int Adj that I strongly suspect is the bias adjustment for the main intensity control, VR8.
Have a squiz at the manual for the trace intensity adjustment procedure that normally goes something like: the trace should just be invisible with the main intensity control set to minimum.
Let us know how you get on.
