Hi Davedotco,
Right, have a soldering iron and reckon I can do this. However, one stupid question. The boards in there now are for bumping up a stylus signal. Therefore, it makes sense that they only apply to the phono input jacks. Thus after removing them and jumping the pins, I need to feed the CD signal through the phono jacks? Or, is this a 2 stage amplification board where the aux and tuner get some amplification and the phono inputs get extra amplification?
bottom line, with cd connected to the aux inputs, do I see a benefit?
