close to finish my 1073 knockoff but there´s one thing. that damn hf rolloff in the eq section (around 6dB down@20k!!!)
allready tried the mod from phoenixaudio
http://www.phoenixaudio.net/tipsntri.htm
but it turned out that the critical parts are the 470p (1st inverting amp) and 108p (2nd inverting amp) feedback caps (from output to input)
removing these or decreasing capvalues solves the prob...but then the circuit is not stable (oscillation at high eq boosts) ...argh
any advice? where are the neveslutz? :green:
steff
