Gainclone high ferquency difference

Seba91 · 27th November 2009, 01:42 PM

Hi!
I have two gainclones one I built completely and kit.
My problem is that kit gainclone plays high ferquencys great (maybe too bright) and one I built lacks them, what can be the problem? I even switched speakers.
I dont have any high/lowpass filters in them
I try to find websites where schematic I used is.

What IC's are you using? are both build the same way ?

LM3886 kit one is nearly like mine, input connection to ground with 100nf condensator and 2kohm resistor might be the problem, well I was planning to build new one anyway...
