good evening ladies and gentlemen,

first the introduction: some of you may know me from AH, for more detailed
info see my homepage. i make electro, use mainly analogue synths and am
starting to get into diy-ing via modifying speak & spells, small drum
mahcines and toys.

now the question. i have a kawai 100f, which is known to have a quirky
gv/gate configuration. i borrowed another one from a friend, which is
modified for standard cv/gate in. so i'm basically trying to
reverse-engineer what is done here. the oscillator not only responds to
cv/gate now, but the filter scaling does too.

i've identiefied most parts (an lm741, tl071, some resistors , switches and
capacitors) but there are 2 capacitors i can't identify. they're small
orange ones, 2 poles, and all they have written on them is 105L if i see it
correctly. can anyone tell me what these are?

i'm trying to figure out what's what here, i believe if memory serves right
the 100f's cv is backwards, and its gate is s-trigger. there's 2 small
breadboards inside with a chip on each, maybe one is a trigger converter and
one a cv-converter. there are also 2 small trimpots inside, and a pot for
the cv-scale and one for the filter scale on the outside. i wouldn't
necessarily have to have the filter mod, but if i can't figure out what's
what, i'll try to copy the whole thing wire-by-wire..;-)

anyway, any help is appreciated. it would be nice to use the 100f as
anything other than an effect machine..
