The Tektronix Type 360 is the "indicator unit" of the 160 series modular scope system. It contains a 3WP CRT (T3100 for SN > 2682), vertical amplifier, horizontal amplifier, and HV CRT circuit. It does not contain the low-voltage power supply, which is a separate component in the 160 system.

Internals

Vertical Signal Path

The vertical signal path starts with a switched compensated attenuator, followed by a 6AU6 differential amplifier stage, followed by a second 6AU6 differential stage.

Horizontal Signal Path

The horizontal amplifier uses a 6AN8 common-cathode gain stage followed by a 6AU6 common-cathode amplifier as a phase splitter to differentially drive the CRT horizontal deflection plates.

CRT Circuit

The CRT circuit in the Type 360 uses a 6AQ5-based power oscillator to drive two 5642 high-voltage rectifier tubes, one for the CRT grid voltage, and one for the CRT cathode voltage. The high-voltage regulator feedback amplifier is made from two cascaded common-cathode amplifiers, each made from one half of a 12AT7 dual triode.A high voltage isolation transformer (1:1) is used to power the CRT filament from the main 6.3V heater line.

Mechanical

Open-frame construction allows the 360 to operate without fan cooling. 360s with SN < 1000 were made using printed circuit boards, later SN are made using the ceramic wiring strip style that is more typical of the 1950s and 1960s Tektronix construction.
