Hi !

I have problem with the high boost on a 1A clone.
When i turn the high boost its not a smooth response, and i have to turn the knob fast all the way up to to 10 to get it to respond.
Its also scratching when i turn the knob (with no audio playing through of course)
Could it be a cap charging d.c in the high filter section?
Its affecting all KCS selections.
Its old caps, new PEC pots, but carbon.

Help is much appreciated!
