Ive got an Audio Research® preamplifier and the bottom of its chassis is perforated with holes. How can I use Rollerblocks with it?
Every Rollerblock set contains three or four “Rollerplates.” These are polished stainless steel plates, which can be used between the balls and your component’s chassis if the chassis is ventilated, irregular, or doesn’t present a good, smooth rolling surface for the balls. Or, you can use them if you’re worried about marring the underside of your chassis through contact with the balls.
