Hi,
oh no, it's me again. ;)
I have a question about the 'ASM-1 mod' that is mentioned for +/- 15 V operation:
First the mentioned 330K resistor seems to have gotten a 220K in V1.0.
According to the ASM-1 schematic the 240K would be replaced by a 560K and the now 220K by 200K.
But what about the 47uF capacitor? As this feeds into the waveshaper section it looks like
it cannot be simply omitted because it is 'redundant'. My guess is that I should put a link
there and omit the 100K from the second saw output to ground.
As I'm not sure if it's OK to include attachments in this list I have uploaded a picture with
the compiled changes here:
