My Linn Axis runs 3.5% too fast (although at a very constant speed). The motor control board contains several ICs (e.g. LM324N, HEF4066BP etc), caps and output stages on a heat sink. I've read that the output stages generates two sines waves 90 degrees out of phase. The motor voltage is during upstart initially high, and goes down to 25-30 volt.How are the artificial sine waves generated? There are two pots, called 10K and 2.2K on the board. Are these for setting the speed, i.e. the frequency of the sine waves? Or for something else?
Anybody familiar with this motor control board?
Thanks in advance
Thomas
