[Station X]

I was faced with this problem recently with one of those "Rugged Radios" used by builders. They use 2 AA cells to maintain the clock and presets. These had corroded and totally dissolved one of the tapered coil contact springs. I slid out the brass strip, cleaned it and soldered what looks like a phosphor bronze coil spring to it. I've no idea where the spring came from. Every time I scrap something, all the springs it contains get slung in to a plastic box and this was one of them. I could have used a spring taken from a battery holder, but preferred not to destroy one.
