Thorens Headshell for TD1600: Installation Guide

Quick answer

To install the Thorens Headshell for TD1600/TD1601, align the headshell pins with the tonearm socket, tighten the collar, and set the correct overhang using the supplied slot. The process takes about five minutes with basic care.

Step-by-step installation

1. 1. Remove the old headshell: Hold the tonearm steady with one hand. Unscrew the locking collar at the base of the existing headshell (usually a quarter turn counter-clockwise). Gently pull the headshell straight out of the tonearm socket. Set it aside. Common mistake: twisting the headshell while pulling can bend the pins. Pull straight out.
2. 2. Prepare the new Thorens headshell: If you are installing a cartridge, mount it to the headshell using the two supplied screws. Tighten them just enough so the cartridge does not wiggle. Do not overtighten — the threads are fine and can strip easily. Check that the cartridge body is parallel to the headshell top edge when viewed from the side.
3. 3. Insert the headshell into the tonearm: Align the four pins on the headshell with the four holes in the tonearm socket. Push the headshell in until it seats fully. Tighten the locking collar clockwise by hand until snug — do not use tools. If the headshell does not slide in easily, check that the pins are straight. Forcing it can damage the socket.
4. 4. Set the overhang: Loosen the two screws that hold the cartridge in the headshell slots. Slide the cartridge forward or backward until the stylus tip aligns with the overhang gauge for your TD1600/TD1601 (typically 15 mm from the mounting hole center). Retighten the screws evenly. A common mistake is setting overhang by eye. Use the gauge or a protractor for accuracy.
5. 5. Balance the tonearm and set tracking force: With the headshell and cartridge installed, zero the tonearm counterweight so the arm floats level. Then set the tracking force to your cartridge manufacturer's recommendation (usually 1.5–2.0 g). Confirm with a stylus force gauge. Do not rely on the counterweight scale alone — a gauge is more accurate and protects your stylus.
6. 6. Verify alignment and enjoy: Check the cartridge alignment using a two-point protractor. Adjust the cartridge position in the headshell slots if needed. Play a test record — listen for distortion or skipping, which indicates misalignment. If you hear sibilance or uneven channel balance, re-check the overhang and alignment before adjusting anything else.
