I know this is quite an old thread, I would rather post in a thread which is related rather than there be hundreds of similar threads. I did try to find any other posts about this, but this was the one that came up.
I have recently bought a Genrad 1433 -G (0.1 - 100K 7 decade) box very similar to Dave's. Some of the switches are quite stiff to the point that I feel they will break, some of them feel magnificent. I thought it might have needed a bit of movement to free up the switches, but even after actuating the stuck switches close to 100 times each, they still feel very stiff.
The resistance is pretty darn accurate so I am not wanting to just jump in there with WD40 or anything, but I am worried about the stiff switches and am hoping someone can give me some advice on what to do.
I notice (like on Dave's) there is some grease / lubricant on the contacts, if I clean the contacts, what should I put on there? The manual says to clean the contacts, but nothing about what sort of lubricant to put on after.
Thanks in advance
