I have finished the assembly to night. just waiting for me PSU caps and transformer. but i soldered inn C3, and have only VR1 200ohm.
so how much effekt will that do? and VR1 is DC ofset? VR2 bias?
but what about VR3?

I audio, the effect is significant. you can't get the zero output with 200Ohm vr1 with C3 installed. remove C3 if you can't find a 2k ohm

one improment must be the solder eyes. it is very smal space for the solder to atatch on the back side of the boards. it vil work with a very thin solder iron. i hadd to solder resistors from the top.

Hi AudioSan

Could you explain a little more about your problem? We have no problem in assembly the boards from the back side. If you can solder from the top side, why can't solder from the bottom?

the soldering area around the holes was to smal for my iron. transistors was fine. but resistors was a pain. but it worked out maybe get a thiner iron tip.
