The tweeter cuts in and out (mainly out) when the trim knob is turned, and spontaneously when playing. I'll try some contact cleaner on the shaft.
Assuming that does NOT do the trick (after all the thing is almost 25 years old) is it better to replace the LPad with a new product? Any good matches? Any tips for whether to access it by removing the rear or front baffle.
I might even like to bypass the controls and add fixed 2-resistor LPads to tweeter and midrange. Maybe -1dB tweeter and +1dB midrange. Any values that have worked?
Thanks. BTW, this is quite some speaker. I'm not in love with the treble, and the midrange is a touch laid back, but the strength and warmth of the bass is outstanding. And it likes to be turned up.
