TD321
速度調校
I have been using my TD321 (with SME 3009R) for almost 20 years. It is
still working fine. Recently, I built my own Turntable Speed Monitor to check
the speed of the turntable. The turntable motor speed can be adjusted
by the two VRs, 33.33 and 45 RPM, on the circuit board of the TD321.
Now, I can adjust the speed of my turntable accurately.
