Thanks for jarring my memory, now I remember why I bought a VPI speed controller and a KAB. Stop watches ?? To each there own ... All the best.
Measure My Turntable Speed
I've been told that a very accurate way to measure the speed of a turntable is by using a test meter set to khz, placing the positive terminal into one of the outputs of the phono stage (or tape output), the other to the ground and then play a 1000hz test track of our a good quality test record... If the table speed is good, the reading should be very close to 1khz...
Ever tried this one?

I haven't read the whole thread, but I could never get my speed set on my Bix with the KAB unit. I sold my KAB strobe and bought the Digistrobo which claims my system is locked in perfectly and stays locked in rather tightly over time. I wonder if the KAB strobe is much more sensitive/accurate or if it is too accurate; I could never dial in a stable speed with it...it was like trying to balance an egg on a razor when setting the speed. ???

The 'Digistrobo' looks alarmingly similar to laser tachs available on the ebay for a lot less than 150.00, such as this one http://cgi.ebay.com/Non-Contact-Digital-Photo-Laser-Tachometer-RPM-Rotation_W0QQitemZ160352588438QQcmdZViewItemQQptZMeters_Testers_Probes?hash=item2555c25296&_trksid=p3286.c0.m14 and many, many more. After seeing the audiophile version in a catalog, I bought one of the ebay iterations to try-and it does seem to work as advertised-at least, it's accurate compared to my strobe disc. In fact, I made a little stand for it and it has a permanent spot on my tt plinth, ready at a moments notice to check stylus-in-place speed. I've got a feeling-okay, I know- that this is just another case of audiophile product re-labeling, with the commensurate 6x price bump. Just like most electronic VTF scales. |
I do have the KAB Strobe and disc. I am not 100% confident on its accuracy. I used Feickert's Adjust Pro + and his test record. When Adjust tells me I am dead on, KAB says otherwise by a significant amount. I ended up using a Fluke DMM and measured the 3150hz tone on the Adjust test record after communicating with Feickert. He seems very confident on the accuracy of his test tone frequency. |
