If you have a schematic, it shouldn't be too difficult to locate the buggers and parallel them, to bring up the bass. I've done this same trick on a number of audio components, and it worked every time, especially with a Pioneer VP-1000 LaserDisc player and an outboard CX decoder. Makes quite a difference for bass heavy SPFX. -- Chuck Forsberg WA7KGX ...!tektronix!reed!omen!caf CIS:70715,131 Omen Technology Inc 17505-V NW Sauvie Island Road Portland OR 97231 Voice: 503-621-3406 Modem: 503-621-3746 (Hit CR's for speed detect) Home of Professional-YAM, the most powerful COMM program for the IBM PC
