Christmas holiday plan: repair a 60s turntable

Jan Cumps
Jan Cumps over 2 years ago

I have a turntable from the mid-60, Thorens TD 124. It has a mechanical issue: the speed selector has a worn-out component.

This holiday I'll see if I can fix this. These tables, and the components, go for crazy prices (check ebay for anything related to a TD 124, it's a strange world out there).

The worn component is part of this contraption:

    It turns out that I'm lucky. The part isn't worn, but lost grip. Symptom: the outer ring should turn the speed switcher, when it's turned by the plate steel belt. But it slips. Cause: the speed switcher…

    Glad it's sorted! I was planning on visiting two days ago, and would have reached out to you closer to the date to see if you were around. Planned it about two months ago as an Xmas time off thing, but a friend fell seriously ill a couple of weeks before (fortunately almost recovered now) so we had to cancel. Will hopefully try to visit sometime in the next few months, because it's been at least 3 years since I visited there.

    Checking the player while it's standing up. Washers and circlips are replaced.

    Test to see if the idler wheel engages at the right height of the tapered axle:

    Please do, I'd be happy to meet up and show you around.  Not sure what has changed in the last 3 years - the Bombe went there in 2018 so you probably saw that, EDSAC is more finished, Heath Robinson is up and running and there's typically a rotating gallery.  You'll still get a chance to better your score on Manic Miner!

    Looks like you spent some elbow grease and wiped down surfaces or was the plastic cellophane removed:)

    Grinning it was clean, just gathered dust from being stored away for about 3 years.

    I lost the photos of how it looked like when I bought it. It was sitting inside a tent in a yard sale, on a table in a puddle of water.

    I also lost videos and photos from when I took apart the motor and the complete tonearm.
    Still surprised to this day that I managed to get that tonearm (and it's plethora of ball-bearings) back together. Cheapest replacement I can find online (with issues) is above 400€.
