Douk AudioNobsound D60 50 / 60Hz Stroboscopic Speed Strobe Light Tachometer Disc for Turntable LP Record Player

Other than the documentation (hard to read), this is an ideal strove setup. Since I have both a quartz locked direct drive unit and a belt-drive unit, I was able to test the strobe out on the unit I know is accurate before using it to calibrate the belt-drive unit. It was dead-on, and made it easy to adjust with the 33 1/3 and 45 RPM on my belt drive. Nice build quality, too!

This worked fantastically at checking the speed for 331/3 and 45 rpm rocords on my my Music Hall MMF 1.5. It is the cheapest option that I have found. It has solid metal construction and is simple to use. Highly recommended.

Not much to say, works great, well built. Just needs a power switch. Kinda dumb that it doesn't to be honest. Even if it were just an inline one on the cord.

I had to get a strobe since my spendy razr phone shamefully can't run the strobe apps, or even the accelerometer based RPM apps, and this appears to be the best option. I do recommend this if you need a strobe that just runs off your ac line frequency. It looks like a white light when running, no visible flashing which was nice. The Tach disk that comes with it is more useful if your on 50Hz power since that is what the marking lines are for, the 60Hz markings are small dots which are hard to see. The power cord is also very short and I can only use this with an extension cord because of that.

For the cost the Nobsound D60 stroboscope is very well-made, it far surpassed my expectations. The disc has no gaps (mentioned earlier by another reviewer) and is printed correctly, made out of metal heavy enough to properly sit still on the platter, making it very easy to see the appropriate dots moving left or right or being steady when speed has been set correctly. I had already set my speed using a cartridge alignment tool and chronometer and this confirmed my settings. Unless your turntable has the ability to set 33 1/3 and 45 rpm with separate pots (mine does not) or electronically, only set 33 1/3 (or re-calibrate every time you change speeds but that may result in premature wear of the speed adjustment pot and drift)

Easy to use and seems to produce accurate results. The included strobe disc is only about the diameter of a record label so you can put it on the record and test while playing the record.

I bought this for calibrating my Clearaudio Concept TT.The strobe is great, no setup, auto senses your power's Hz and works flawlessly.The issue is the disc that comes with it.Thought it would be perfect, but the printing on the disc makes it hard to read.It the dots that one reads at 60hz, there is a break, so every revolution you have a break in the dots at 33.33 speed. This makes tracking the dots very difficult.Normally you have an unbroken stream of dots or marks on the TT or disc for calibrating.This disc is very small and printed dots at 60hz have a break in them where they print "33 60hz" which ruins it. They also appear to not be in a perfect circle on the disc. Having the break makes your eyes have difficulty staying on the dots to see if they're stationary. If the dots were unbroken, this would be a perfect tool for calibration. As it is, it's a mediocre tool at a good price.

It works Fine!

Really easy to use , made nicely

I would have given this review zero star if without Amazon's return policy.The strobe worked in my first attempt but after about 2 minutes of use, I felt the 12V adapter to be very warm when I touched it. The next day, I use it again on my second turntable but this time, there was no light from the strobe but I also did not feel any temperature from the AC adapter. I connect the strobe on any power point and it was the same. In my case, this product fails easily - unreliable.

ストロボは、綺麗に速度を示すが、この製品にはSWが無い、常に点灯させる必要は無いのでon.offのSWが欲しかった。

It gets the job done, nice piece for the price.

Preformed well. Is well built. Good value.
