Vintage Synth Repair

hey guys,

i've fixed EVERYTHING on my arp except for the noise generator. at
least, i think it's broken. i've replace the transistor (Q9) that was
nonfunctional with a new one, and now i get some noise, but it seems
to be pitched, and in an oscilloscope it kinda looks like a sine wave
with square tops and bottoms. this would be cool if it was tunable and
controllable by the keyboard, but since it's not it's making it kinda
useless. anybody else have this problem? maybe i did something wrong
with the installation. i know i'm close!


thanks,
johnny
