@pbnaudio, what great timing, I was just running it through my mind why something like this has not been available. Will be nice to just look over while system is running and see exactly what it is doing without having to get out the Kab and set up the strobe. Thanks to sgunther for bringing this up.

 Peter, your comments lead me to believe that you have probably installed your tachometer on a few Denon turntables that you have restored. I am wondering whether you find that your tachometer is in agreement with the built in strobe device on Denon dd turntables. Which is to say, when the strobe image is stable, indicating 33.33 RPM, is the tachometer reading the expected value?
thanks.

Yes indeed - the Denon DD's are very precise - I use the Tachometers on the DP80 Professional and the DN308 Professional.  The reading is 33.333 with the last number varying a slight bit,  they all lock in at "their" speed, which can be 33.334 or 33.332 and some at 33.333  The Oscillators are not adjustable on most of them - only the DP7000  and a few of the DP6000 have had adjustable oscillators.

Good Listening

DP80 also allows speed adjustment but I think it disengages the servo.
