Stacked Knobs

[Frank Blank]

I have just taken the stacked knobs off my ACG (they needed a clean) and I've discovered that a couple of them (two out of three of the stacked knobs) had springs between the upper and lower knob, the remaining stacked know had no spring. Are these springs usually to be found between the knobs like this, I suppose I should ask @skelf really. Having done the same previously with the Harlot it had no springs in the stacked knobs.

The springs are there to ground the upper knob to the pot lower ring. It was previously not needed because the knobs were brass but with the move to aluminium John found that they needed the spring to be fully grounded so were added. Should be a spring in all of the knobs. It also depends on the type of preamp the EQ01 is less prone to this issue. John explained why but there is a reason he does the preamps and I don’t.

Cheers Alan. The springs were in the short scale Recurve which has the East UNI-PRE 4K preamp, any idea where I can get a replacement spring?

I actually don’t have any at the moment. I am not sure where John gets them from or if they are made for him. Maybe drop him a line and ask.

I have done just that, cheers Alan.

I received a prompt reply from John, thanks again.
