i remembered that guest said that Roland used in the VCO section 0.1% resistors.
taken from this post : http://forums.adafruit.com/viewtopic.ph ... 6&start=15the 303 datasheet specifies .1% resistors
which would be 199.8k to 200.2k
i'v found a source to them .. http://www.vishay.com/resistors-discret ... -less-pt1/
Vishays factory is here in Israel, if anyone is interested i can try organize a group buy.
