The Tektronix Type O is a letter-series plug-in, designed by Hiro Moriyasu, that contains two operational amplifiers and a vertical amplifier. It was 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.

Prices

  • $625 in 1971 ($4,700 in 2023 dollars)

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.
