Many thanks to all posters.

Interstingly, I had to replace the line filter in my Solartron 7065 too, that went with a pop and smoke, although nowhere near as bad as this one which took out a 13A fuse in no uncertain terms. To be fair to the manufacturer the switching PSU in the 7065 still works perfectly after 30+ years - most switchers seem to struggle to last 1/10th of that.

It seems this filter IS still manufactured and available although at ~ £30 (including shipping) its too expensive to repair an instrument with a broken LCD and battered case (I have a use for it on GPIB so the lack of display won't matter). I've opted for a cheaper filter / fuse unit (from RS) that I will 'bodge' to fit and wire for 240v only.

Many thanks, dave
