Wow, Jim, I have one of those!(somewhere)
I purchased it back in the late 80's when I had time to be an audiophile (Mark Levinson, and AR tubes, Magnaplanar, Linn Sondek, etc) RECORDS!!!
I wonder how long the shelf lif is on one of these. Gotta go to the basement and try to find the dang thing.
My doser-less modded Rio SJ already has a some static charge. I can only imagine this winter with 20f temps, and 30% humidity.
So, assuming the OP and I have a Zerostat in our trembling hands, where do we discharge?
