CASSETTE PARTS ALIGNMENT
1, MOTOR TURNSPEED: Adjust the screw at motor back side to make the output signal near
3KHz while play the 3KHz standard tape. It used frequency meter connected output.
2, HEAD AZIMUTH: Adjust the screw of head azimuth to make the 6.3KHz signal to maximum.
It play the 6.3KHz standard tape and used VTVM connected output.
