Re: DSA 602 acting up (power supply?)
Years ago I had a service guy for our ultrasound machines show me a trick.
This was for cleaning contact fingers on printed circuit card edge
connectors (not on anything like delicate switch contacts). He would use a
dollar or other currency he had in his wallet and would pinch it around the
edge connector fingers and rub it back and forth a few times. Seemed to
work. Paper is fairly abrasive so it makes sense. Has anyone heard of this?
I have used the idea and never had a problem with rubbing off the plating.
I would not do this on the contacts in those Tek switches.
