This is a long shot, butt I'm desperate. I have two superb Solartron
7061 digital voltmeters. One works perfectly, the other one needs
repair. Apparently Solartron has been split off, merged, renamed,
several times since they made these voltmeters. No sign anywhere on
the Internet of the service manuals.

I'm hoping somebody here has some hints where I could enquire for same?

Regards,

George
