...I just picked up one and it doesn't have the owner's manual...I've had Duals before but it's been many years, there's a few adjustments I'm kinda guessing at. And it looks like there's a small piece broken off the removable cartridge mount but I think I can fix that. I've found the service manual I can buy off the 'Net but can't locate the owner's manual. Anybody out there with one of these classics and an owner's manual?? Thanks!!
