[sdiy] buchla 112 help

[jon schatz]

i've got a 112 which has two issues.

1) the pressure sensitivity is way too sensitive; it goes from 0v-15v 
without much change in my finger's position

2) if i manage to get a non-endpoint value out of the pressure output 
it's super wobbly

i'm looking at the schematic now and it looks like adding a reasonable 
cap in series with r243 should handle 2) but 1) has me stumped. i'm 
thinking that q71 is the part i should consider changing but i'm totally 
unsure.

any help would be appreciated.

thanks,

-jon
