well, i don't think it matters what kind of caps you use for 555s and
decay envelopes. i've had them work fine with polarized electrolytics
and ceramics.
as far as the clocks, mine dip down into the audio range at their
lower end. you should be able to hear a faint whine if you touch their
outputs to the 707 outputs. if you can hear output, they should work
as clocks. accordingly, you can use these clock circuits as audio
oscillators if you use a bigger cap. there is a free dos program
called 555.exe which calculates the frequency of the oscillator when
you type in the values of the cap and resistor.
