Hi, my guess is that no one is reading this thread anymore but I will ask my question anyhow. My 600A came to me in working condition and gives me believable results EXCEPT for the #3 switch. When I push the #3 up I always get a full short... no matter what tube I am testing or where I am on the rolodex. Any ideas? Thanks.
