[sdiy] electrolytic coupling capacitors

[Theo]

Look at the level of the "internal" reference voltage and assume the
"outside" reference voltage to be 0V.
Now mount the caps so that they are polarized correctly based on the
reference voltages.
BTW Usually this means the positive side looks at the circuit.
