Parentheses mini - negative values at Q6?

[Anton K]

Hi there,

I finished my Parentheses Mini these days and I am very pleased with how it sounds. I’m not very experienced in electronics, so I have some questions, I could’nt find in the forum.
The boost does its boosting at above12 o clock. Below 12 is more of an attenuator. I this right? looking for it, merrily I measured around and measured somewhat strange values at Q6.

I got
d 4,8V,
g 2,41V
s 0,2V

at different grounds. (DC-jack, input-jack, pots …) But if I measure the same at the ground of the distortion-pot, I get negative values:

d 0,27v,
g - 2,14V
s - 4,38V

So I wounder if this could be right or is there an error?

best regards,
a.

The distortion pot doesn't connect to ground.

Wow - super fast answer. Well, I try resoldering the pot …

Edit: does not fix it. seems to be somewhere between R9 and the distortion-pot … search is going on
