Hi, x0xerz
I have repaired a x0xsource that was broken. But now it works,
The VCA produces a little white noise and it's pretty unpleasant when we used other x0xb0x... I'm not used to that...
I tried to replace some of the VCA components without improvements.
That said i noticed it was equipped than 2SC945Q and they are not the same HFE better than 945P's . What would be the repercussions on the synthesizer to have placed these transistors, maybe a x0xerz expert opinion?

is that Q30?
Q30 is part of the VCO slide switching circuit.. it's not in the audio path really

Yes it is, it was an example, they are all 945Q, everywhere ...
It's just that i find it rather strange idea as to have built with these transistors. I'm wondering if the problem does not come from there. What do you think? Personally i have never built a x0xb0x with 945Q, i do not know if it changes anything.
