Hi everyone,

Well another Hamfest sees me buying yet another lovely valve based object.

This time is a Cossor model 1232a sweep and marker generator for TV alignment.

I was wondering if anyone know where I could get a manual for it?

I've replaced the nasty old 2 core power lead with and earthed 3 core one, checked and then reformed the main filter electros and away she goes, seems to work quite well.

Must have cost a bomb in October 1955 when she was made, beautiful construction and 8 valves!

Not a great believer in reforming old electrolytic caps. Having pointed that out I did build a reformer onto my PSU and the 1938 Valve tester has one of sorts.

I tend to use it more for finding the modern ones that have a habit of failing or have been sitting a while. They are not as bad as some older ones for loosing "form" & then presenting as a short circuit.

A lot forget about the ones on cathodes, they should go as well.
