Technics SL-DD33 Fully Automatic Turntable
These are robust and very reliable turntables, but as time goes by, they will require service. This page will be updated as issues are encountered and corrected.
1. Automatic arm motion is not working properly.
Instead of starting at the lead in groove, the arm moves way over to the
center of the record.
In this case, the usual problem is hardened grease in the tonearm assembly. The positioning mechanism is a spring loaded plate that rotates on the arm base and contacts the position adjuster. Hardened grease can cause this plate to become frozen. The solution is simply to apply a short spray of penetrating lubricant, or fader lubricant. once the plate is free again, dry up any excess lubrication and put down a few drops of spindle oil. There was never any need for grease here in the first place. The pivot is outlined in red shading. it should always be in contact with the adjust dial. The cueing lifter is another area where grease was place in which it did not belong. spray clean, get working smoothly, and put a drop of spindle oil on the shaft. Reassemble and retest both record sizes.
