Bloch (...!nsc!voder!gino) > Mr Humility *** REPLACE THIS LINE WITH YOUR MESSAGE *** Years ago I had a GE battery/AC-powered cassette recorder. There was a little slide switch in the compartment where the line cord, which was not detachable, went. One day the switch broke so that the recorder ran on either battery XOR AC, can't remember which. I, not knowing any better at the time, soldered the six leads on the switch together. Later on, I found out by accident that the recorder {re}chargered the batteries when it was plugged in to AC!! Also, when the recorder was unplugged, the diodes in the power supply were reverse-biased so the batteries did not discharge through the supply. This arrangement charged carbon-zinc batteries better than a friend's battery charger, so when one of my two sets of batteries went low, I swapped the sets and everything worked fine! Kchula-Rrit
