Yesterday I had the time to try again . Ein built an audio probe like it is described in the building instructions. With the Audio probe i checke the circuit. And on the entrance of the resistor R26 the signal wars normal. But on the other side of the resistor it was massively distorted. Checked with a Multimeter it shows 8.1k.
Could the resistor be damaged so that the audio signal gets distorted in some way?
And if it is damaged: I have several resistors at home. A 10k and a 5,6 K resistor are the nearest. Can I use one of them or should I take some resistorsparallel or serial to get to the 8, 2K?
Thank You ,
