The '''Tektronix Type O''' is a [[letter-series and 1-series plug-ins|letter-series plug-in]], designed by [[Hiro Moriyasu]], that contains two operational amplifiers and a vertical amplifier. | |||
It was [[introduced in 1962|introduced in mid-1962]] and was available through 1973. | |||
The input and feedback networks of the operational amplifiers can be configured from the front panel switches and/or by way of user-supplied components plugged into the front panel banana jacks. | |||
Tektronix made several pre-configured plug-in modules to plug directly into those jacks. | |||
See the ''Accessories'' section below. | |||
Note that one of the accessories is an empty box with mating banana plugs for a user-designed circuit. | |||
A mode switch selects the display to be taken from either op-amp's output, or the vertical amplifier input. | |||

==Internals== | |||
The opamps are implemented using two [[12AU6]] as a differential pair followed by two systems of a [[6DJ8]] as a bootstrapped cathode follower. | |||
The vertical amplifier also starts with a 12AU6 differential pair, which is followed by a pair of [[2N1143]] 200 MHz transistors. | |||
