CAUTION

Care should be taken to avoid striking the face of the tape heads with any hard object and this does include the cartridge itself, which can dent the head face if inserted a t an angle. Use of a hold-down spring and side-guide rail is highly recommended. Penetration of the head into the cartridge should be set a t 9/32-in. Excessive penetration will cause faster head wear and possible tape skewing.

QUI K-K ITS

QK-114 installs two no-mount B-size heads on a cartridge transport. I t includes micrometer adjustments for head position, a cartridge holddown spring, and side-guide rail to control :artridge insertion.
