I really like the overall character of it but I'd like to tighten up the bass a little bit. I might want to cut off everything below 60hz really..it has a HUGE spike down there somewhere...scared the hell out of me when I saw my speakers flap like that!! I'd also like to squeeze a little more gain out of it if I could. Any ideas? Here's the link to the schems...

It's on pages 14 and 15...careful...they overlap! Also, how would different pot values affect this circuit? They're all 100k and that just seems odd to me. Thanks!
Hi kiehano.
What you should do to control that excess subsonic frequency is go to the power amplifier (betamanual22.jpg) and replace C1 (2.2uF) by a .22uF.
I noticed that late last night. I thought that was the cap I'd be looking for but I wasn't sure. Now where would I insert a diode or 2 to eek out a little more gain? I'd obviously have to do it for each channel and I'd want it to be controlled by the gain pot.
