ABSTRACT OF THE DISCLOSURE A testing apparatus for cassette type tape recording and/or playback machines has a cassette shell for mounting on the machine in place of the regular tape cassette, the cassette shell having driven means such as spools displaceably mounted within the cassette shell and adapted to be engaged and displaced respectively by the forward and rewind spindles of the machine when either of such spindles is actuated. Indicator means indicate the torque applied to either of the driven means by virtue of an indicating pointer adapted to move over a scale from a central rest position to which the pointer is spring biased, flexible means such as leader tape interconnecting the pointer to both of the driven means. Preferably the spring biasing and pointer are integrally formed in a T-shape with a pivotal mounting at the junction of the T such that the arms bend resiliently upon displacement of the pointer.
