They recommend a 10uf Polarized\ncap. The cap MUST be high enough\nso that its impedance does not cut\ndown the audio signal. See my docs.\nA 10uf (or higher) is OK. a 1uf will NOT\nwork. Impedance increases exponentially or\nlogarithmicly\nas values go down in capacitance.\nValues even as high as 1000uf will be ok.\n(possibly higher). Being too low, will\nresult in impedance / esr (or aging of \ncap).\n\n
