On my 29lx I still have a low dead key. I've added lots off capacitance on top of the 68of (I think that's the value).. like 220of added all ready.. and I . Also have a really low resistor value on the swing mod portion of the installation. Every thing works great, it's reading 70 watts peak on my crappy meter the dead key is just low.. is it possibly ive added to much cap?
