 The '''Tektronix 3A8''' is an operational amplifier plug-in for [[560-series scopes]],  designed by [[Roy Hayes]] and [[introduced in 1965]].
 The 3A8 contains two operational amplifiers and a vertical display amplifier.
-Each operational amplifier has external inputs and outputs.  Input and feedback resistances / capacitances are separately switch-selectable to provide a variety of opamp functions.
+Each operational amplifier has external inputs and outputs.
-External components can be substituted by way of front panel banana sockets, which also accept special purpose adapters (see ''Accessories'').
+Input and feedback resistances / capacitances are separately switch-selectable to provide a variety of operational amplifier functions.
+External components can be substituted by way of front panel banana jacks, which also accept special purpose modules (see ''Accessories'', below.)
 The display amplifier can be connected to the output of either operational amplifier, or an external input. The input can be AC or DC coupled and can be inverted.
