一台 [yī tái] is used for most nouns ending with 机 [jī], particularly when the object is heavy or has a large base. For light and portable equipment, the measure word is 一部 [yī bù], for instance with 电话 [diàn huà, telephone], 手机 [shǒu jī, cell phone], and 照相机 [zhào xiànɡ jī, camera]. However, for 订书机 [dìnɡ shū jī, stapler], 一台 [yī tái] is more often used than 一部 [yī bù]. 

For an artistic performance on television, 一台 [yī tái] is more often used than 一场 [yī chǎnɡ], whereas for a stage performance in a theatre, 一场 [yī chǎnɡ] is more often used.
