The Tektronix Type 59 is a 400 kHz amplifier for 560-series scopes. It was introduced in 1960, and at $50 (2015 value: $398) it was the lowest cost model of the 560-series plug-ins.

It does not have a calibrated input attenuator. The Type 59 signal input is a pair of banana plugs.

The manual says

The forward end of the chassis has been left free of circuitry in the anticipation that a user may wish to install additional circuitry to fit the Type 59 module to his own special application.

Key Specifications

Bandwidth	400 kHz
Deflection	~ 1 V/Div
Input impedance	250 kΩ

Internals

The Type 59 plug-in contains two tubes, total. Both are 6BA8 pentode/triodes. A triode cathode-follower buffers the input. Next is a differential amplifier made of two pentodes. The remaining triode is used as the trigger pickoff cathode-follower. The heater of tubes are supplied with 6.3 V_AC from the mainframe.
