back to the TD150 dept.
Now begins the journey with this TD150 Mk II. The agenda is as follows:
- Receiving inspection
- disassembly and detailed inspection
- cleaning and repairs
- fabricate new armboard
- assembly with no modifications, adjustment
Play and listen
- Play the table for a time with no modifications
- Compare the table to the modified TD160
- Compare the table to the Teres
Begin a systematic modification program
- Maintain original suspended layout but with significant upgrades
- armboard experimentation (different materials)
- power supply experimentation (does the motor run smoother at 80 vac than 110
- redesign the plinth for greater rigidity and damping
- redesign subchassis frame for greater rigidity and damping
Listen to some records.
Step 1: Receiving
The process begins
Looking at the TD150 subchassis frame. Some notes and comparisons to
its successor, the TD160.
Testing the subchassis for deflection under load. Then comparing to
the TD160 subchassis by the same method.
Some ideas for a more rigid subchassis frame.
Looking at the TD150 suspension......and what to do about it.
Clean-up and prep
Step 2: Play and listen before the upgrades
Early listening impressions
Step 3: Making the modifications
analizing the new subchassis frame
something significant is discovered...!
