I am looking to purchase a stacker spindle for my Dual 1009. I am also interested in purchasing the 45 RPM stacker spindle and the single play LP spindle. Thank you.
The 45 RPM stack spindle is most likely available through Gary Stork at www.thevoiceofmusic.com But the LP stack spindles are by now all suffering from deteriorated rubber parts, so good luck finding one that works.
The Internet is a marvelous thing, however it's not a good substitute for actually being there.
Also don't be shocked at the price asked for the 45 changer spindle. They are rare in working order and in very high demand. Expect to pay $50-$60 for one.
