cat walks over headphone wires = hummmm
cat walks away, I reach for cat= hmmmm
strokes cat=hmmm, hmmm, hmmm
so the chain of components can change order but cat is still the errant component, I believe he has grounding issues but when I approach him with the meter he flees! Would a copper collar to ground fix this?
Anyway, I will carry out this experiment with the second himalayan to see if it's just a single faulty cat or a problem with the make.
I'll report back later when I catch him.
