Well yes and no. Some parts do the same and other have no ability to show you anything. The frequency counter shows you a digital readout of the frequency of the signal and it counts the amount of events within a precise 1 second setting. This means Cycles per second or Hertz. It can not tell you anything about the wow and flutter figures.One more question, is a frequency counter and a wow and flutter meter the same thing? I think I started using them interchangeably by mistake.
The LFM39A specifically shows the tape speed as a drift amount away from the precise internal crystal clock 3000Hz or 3150Hz depending on the settings.
A good machine should give a drift that sits at the center position which is exactly 3KHz.
What a wow and flutter machine can tell you even more is the condition of the transport- does the wow appear to be cyclic then it could be burned out fields in a reel motor. If there is high wow and flutter beyond normal then you may have tension or bearing problems. In finding out about the AMSoil I use which is a synthetic, I had observed a great amount of decrease in the wow and flutter of a deck. Some that measured .055% when after oiling measured .025%. People ask me why I press on to tell people to use this oil as expensive as it is. Well look at the numbers. No other oil- Triflow, Zoom Spout or others do this. When sliding a capstan shaft back into a bearing the human hand can tell right away what is happening as it feels smooth as silk. Now I have had amateurs send in decks that the thrust play was taken out and it was tight- wow and flutter goes through the roof. These people do not ask nor know what they are doing- these are the most of the E bay people selling you a deck.
