Unfortunately the degree of flutter is so pronounced that this method suffices at present!

"wow and flutter" covers a wide range of speed anomolies. What do you understand by these terms? Is it more wow (slow variations), or more flutter (fast variations)? A bit of both? Very roughly how many times per second does the speed vary up and down?

I did mention the possibility of "stiction", which is a tape related problem. It can sometimes occur at one tape speed and not another. Have you eliminated this?
