I tried one of the magnets on the bottom/positive contact and it works perfectly! That must be an older one huh, because I don't have a spring on the positive side.... I don't see why the flat top Sony vtc5's aren't working by themselves...... it looks like it makes perfect contact w/o the magnet? Oh well as long as it works..... I was curious about the solder that someone used.... I'd like to see how much and where to add solder?
Edit : oh I see .... You added solder to the upper / negative contact? Right?
That is correct , i just dont like magnets
