As if I don’t have enough audio stuff already, I got curious about trying old school records and asked my father in law for his old one(s). The first he gave me was a reasonably modern Technics. Works fine. Kinda boring though.
The next one though… probably a 60’s era Acoustic Research turntable. Didn’t work, a little water damaged, and in need of some TLC for sure.
A little research showed a bit of a cult following though with a number of folks showing how they had restored their own turntables. So parts are available and upgrades ripe for the picking. Yay! Project!
The T-Frame is a stamped steel unit that makes up the sprung portion of the turntable. (The platter bearing and tone arm bearing as well as the motor assemblies are suspended by foam-damped springs.
You can see two motors actually. The left one is actually a starter motor that helps get the platter up to speed from zero rpm. It also makes sure the primary motor spins in the correct direction as it doesn’t necessarily do that on its on. Other things to note are that the really rudimentary shielding on the motors as well as the wire nuts. Did not expect to see those outside of a wall outlet.
And the inner platter upside down to show the bearing and the shaft. Notice the spherical ball bearing at the end of the shaft. The bearing and shaft just needed a little cleaning/buffing plus a few drops of oil to spin smoothly again.
You might have noticed that the plates were both fairly pitted and not exactly smooth. I actually ended up using a headlight polishing kit with pretty good results:
I bought a new Shure M97x cartridge along with new tone arm wire to finish off that part of it. Also, I milled a hole for an IEC so it would be easier to plug in and out. Also, the power cable was pretty old and ratty anyway.
Unfortunately, I messed up one of the pogo pins in the tonearm while soldering in one of the new wires so had to order a new one. Once that comes in though, it should be quick work to get this thing working and playing music! Now… just need to find some records to actually play!
