Ah, ok, that makes sense. Thanks!

I think Tom Adam left one end of each of the four resistors mentioned sticking up with a wire soldered to them, thus avoiding having to cut traces. This isn’t mechanically rigid and risks breaking resistor. I prefer to solder the resistor into the board at both ends, one end having the wire snugged under it, for mechanical strength. That means you have to cut the four traces. This is DIY! It’s up to you.

So it’s possible to build this without cutting the traces? No issues or other workarounds to make it work that way?

Richard,

Just finished mine. Brilliant! Thanks for the instrustions;-)
I built mine without cutting any traces, but I have some resistors standing up.
Just for the records, don’t forget the 150K’s at the input, results in some strange oscillating sounds…
