IM Distortion Analyser

[Alain Dupont]

Hi to all,

Did any of you build the 1PPM IM Distortion Analyser from Richard Crawford ?

I have assembled it with the PCBC-6 from AudioXpress and I would like to
precise a few points:

1)- I would like to know the values of R108 and R123, as they are not specified ?
2)- On the schematic Figure 5: R126 is 4420 Ohms on DC Output.
3)- Figure 13: a cap C2... under U102 is : 0.1µF and should be labeled C2x

Thanks.

Best regards.

Alain.
