Prattman Cave

I’m on a tear, reorganizing my office and the space that I suppose should be called the media room. Going through many long-buried things, I was reminded that I used to make DVDs.

Remember when the music and movie industries were so concerned about recordable media? They were convinced that people burning their own CDs and DVDs would destroy their businesses forever. Now, they couldn’t care less about physical media.

Revolutionary Tests

I have read many varying opinions of original Thorens turntable belts vs. Thakker belts. Using an RPM phone app, I made my own comparison.

The Thorens belt in my TD-166 MKII has been installed for about six months. It spins 0.49% fast above 33.33 rpm.

The new Thakker runs 0.73% slow, while the graph appears to show less flutter than the Thorens belt. Running slightly fast is generally considered to be preferable to slow on a belt drive turntable. The reason why would take too long to explain.

My direct drive Technics table doesn’t have a quartz-locked motor to guarantee speed accuracy. It spins just a tiny bit slow, with noticeably less flutter than either of the belt measurements.

Turntable belts always stretch with use. I’ll leave the Thakker installed in the Thorens table and check the speed periodically.

Those graphs are reminding me to make one of my occasional Kardia heart checks. No flutter here!
