I agree with the KAB. It is all I have used for the past few years until Origin Live’s LSC upgrade(Light speed control) and now I have no noticeable variation. Where are you located?
Best tools to calibrate TT motor actual speed?
A fellow member, Lewm , was kind enough to sell me his old Walker motor controller for my Nottingham Analogue TT.
It is in good working order but now I find I need to acquire a method ,or tools may be best phrase , to calibrate my TT motor speed exactly.
Never having any adjustments available for TT motor speed it is not something I had given any thought to.
Lewm did mention a KAB strobe which uses a disc and a battery powered strobe.
Also a quick perusal reveals various manufacturers of marked platter discs where you would use a mains powered light ( to establish 60hz I assume) to check actual speed.
What does anybody here use or has used in the past that is easy, reliable, accurate and fairly priced?
Thank you

Hi Uberwaltz, I too use the KAB Speed Strobe. It can be purchased from various online sellers, but as you may have already discovered it costs $110. (Mine was "only" $90 when I purchased it about 10 years ago). An alternative approach costing almost nothing is described here: https://www.vinylengine.com/strobe-discs.shtml Regarding the mention in the article of using a "standard tungsten room lamp," though, as you'll realize such things are no longer made (note that the article was written in 2002), and I'm not sure that they or their present day counterparts would provide enough contrast within each 60 Hz cycle to serve the purpose. What I believe would work well would be to use an ordinary neon-bulb type "AC tester" to provide the illumination, connecting it to the AC with an extension cord. Best regards, -- Al |
