Was working on my "new" C-70 this afternoon. Replaced some resistors and Zeners because of corroded legs (Sony glue), one Zener in the phono PS was almost completely gone. Replaced a lot of caps, reflowed a lot of bad solder joints, cleaned everything nicely afterwards and adjusted all parameters (never had a preamp before with such an extensive adjustment procedure). Hooked it on my M-2 and it worked . CD sounds great, the "normal" phono input works, too. But, :scratch2: when using the "Disc Direct" button the volume is much lower and the sound comes equally distorted in both channels, either with the MM or MC inputs. What could cause this problem and where to start?
