STANDARD MAINTENANCE
Tape Head and Capstan Cleaning
Whenever a unit is brought in for service or repair, clean the tape heads, capstan drive shaft and ali other
tape handling surfaces touching the tape to ensure proper tape run and optimum frequency response.
Use a cotton swab dipped in head cleaner or denatured alcohol. Wipe dry.
Tape Head Demagnetization
Azimuth Adjustment
4. Azimuth adjustment is normally only required when the head is replaced, or for cases of cross-talk
and poor high frequency response. A test tape is required for such adjustment.
2. Connect a scope or VTVM to the right channel output. Insert a test tape into the unit (Use a test tape
such as TEAC
MTT-114, MTT-115). Adjust the azimuth adjustment screw for maximum
output onto
the right channel. Use glyptal or other non-hardening cement to lock the azimuth adjustment screw.
