ADJUSTMENTS
CASSETTE MECHANISM
General Remarks
• Before attempting to adjust the mechanism, wipe clean all tape-contacting surfaces (pinch roller, REC/PB
head, erase head, and capstan), as well as the contact surfaces of the driving parts (motor pulley, flywheel,
pulley, belt, and clutch assembly), with a piece of soft cloth moistened with denatured alcohol. Grease stains
may cause trouble.
• Never use a magnetized screwdriver for head adjustment.
Equipment Required
• Oscilloscope
• Frequency counter
• Screwdriver (Plastic type)
• Test tapes MTT-113C (TEAC) or TCC-111N (TEAC)
