This is something we all know about, but if you're like me, it can still happen. I'm talking about leaving batteries in sets whilst they're not in use. I went to have a play with one of my nice big transistor sets, went to switch it on, nothing happened, opened the back up.. white powder everywhere. Luckily on this occasion I was able to completely remove the offending oxide and the terminals were not damaged, they cleaned up lovely with a fibre pen and then given a wipe with a cotton bud soaked in Servisol Super 10 contact cleaner.

I've now gone through all of my battery trannie sets and removed the batteries. Don't hesitate, do it now if like me you have trannie sets with batteries in them!
