Tale of 3 idlers
Stock 65 year old idler
Audiosilente custom aluminum with rubber ring
Classic Hifi aka Classic Turntable Company based on the original design
Which one works the best? Just a couple of metrics, speed adjustment and W&F and of course is there any audible noise?
The original wasn’t presenting any issues, extremely quiet good W&F, under the original Garrard specs, that’s probably due to the CTC eddy brake, the original was a bit wobbly. But hey 65+ years old, it needs replacement right? Well here’s the rest of the story
Purchased the Audiosilente version first because of my experience with their products for the TD124, excellent stuff.
Immediately upon the installation there was a problem, considerable vibration, took the platter off to make sure the alignment wasn’t off or something like that, and just holding it against the motor pulley and the vibration is obvious.
Purchased from Ray at CTC and he said let me replace it with one of ours based on the original design.
Installed the CTC idler and it’s slightly thicker (vertically) than the original so the pulley was adjusted accordingly. Excellent no noise and speed/pitch is easy to adjust, but W&F is higher than the old original….This testing is done with an actual vintage W&F tester, and I’ve noticed it’s getting better with use, probably less than 15 hours on it so far so time will tell
I’m running a 1 inch wide black rubber belt around the platter, so there’s no idler sound from the platter, there’s actually none without the belt, but figured the belt would dampen any ringing…
I’ll post updates as time progresses, have a couple more mods, and additions coming so stay tuned
