Hello all :wave:
I finally got around to modifying my SL-1200 MK2 table. In its stock form it's a fabulous performer but its main weakness is the wiring.
The arm itself is nothing special but I really like it for what it is and feel that it wasn't worth upgrading.
The reason for this rewire is due to the inferior tone arm wires (tin plated copper??) and the cheap cabling / rca plugs.
A single continuous run of wire will eliminate five contact points, three of which are in the tone arm / headshell assembly
and two on the circuit board underneath the tone arm pillar.
NOTE: This rewire can be reversed but is intended for those who don't mind a "fixed headshell" style.
A single run of 28 awg x 4 Discovery tone arm wire from cartridge pins to preamp was used. Also, a Jelco HS-20 headshell
was purchased because adjustable azimuth is required for this mod.
Materials required for insulating the wire and interconnect construction (or your own recipe).
- Cotton tubing
- Braided copper shielding
- Nylon jacket
- WBT male rca plugs
- Assorted shrink tubing
Required tools for whole project:
- Wire strippers and cutters
- Drill (1/16" and 5/64" bits)
- Basic soldering iron
Getting started:
- Remove rubber base and metal plate - you don't need to remove the plastic base at all.
- You don't need to remove the whole tone arm assembly either, only the arm itself.
- There are only two screws that secure the arm to the pillar. To get to it, unscrew the green circuit board and you will see the two screws.
- IMPORTANT!! Set the antiskate to zero before removing the arm and make sure arm is reinserted in the same manner.
For the cable construction, I found it easier to separate to two L/R signals using individual cables which were then insulated and shielded.
Insulation, shielding and mesh was fed through 4 1/2 feet of the total 6 feet of tone arm wire with the remaining 1 1/2 feet to be used for the tone arm.
Refer to my photos for construction details... I could only upload 6 photos max.
Hope it's not too confusing for you all :headscrat
