I haven't experience any buzz on my 100K TKD pot.Back to the SCG. I am getting some buzz on both channels with a 50k Alps pot at the 12-3 pm positions. It goes away below 12 pm and above 3 pm. What's the experience of others (@Alfi, @Vunce )who are using pots before the SCG? Getting any hum/buzz pickup at various pot positions? It could be the specific pot, but I want to ask before I dissemble it.
