RW and Nsgarch
Thanks very much for your replies. Good information here. This machine is in such great shape, other than the meter settings, I don't want to screw anything up. Sure, I have popped a few tops in my day, but I have also had some problems, especially trying to fix cassette decks, there's so much going on inside. I don't feel confident or qualified to work on this high-end piece. May have to follow my Nak into the shop if I can't figure a way to get these meters leveled. Been trying to find an audio tech here in Denver (via craigs list), so far, no luck.
RW - when you say "why not use the good meter for setting your left channel". Sorry, I'm a bit "technically challenged" here. Not sure what you mean. The left meter is stuck in the red. The right meter, is about level, but is not dropping down to the resting position, far left when no signal is present, or when power is off. They both stay up, the right at around zero, the left, in the red.
RW, you're right, the bias is set by toggling between two settings and zeroing out the meters (max recording level) for each tape type. BUT, right now, I cannot seem to dramatically effect either side.
