But if the circuit can't supply a number of amps, nothing will explode
of course. You're saying that a tantalium could develop undesireable
I wondered about this, because in the 'linear power supply noise questions'
thread, the OP wanted to avoid a polarized cap in his feedback divider,
AC-coupled to ground as it was. In such a circuit there is 50% chance of
a very minor reverse voltage, not to worry about, i'd say.
BTW, nice word, cantankerous. I like the ring of that.
