-The '''Telequipment D56''' is a 15 MHz dual-channel dual beam oscilloscope
+The '''Telequipment D56''' is a 15 MHz dual-channel dual beam oscilloscope produced in the late 1960s.
-produced in the late 1960s.
 It uses a mix of tube and solid-state circuitry.
 In the absence of a D56 manual, the closest manual is that of the [[Telequipment_D55|D55A]], which is an all-tube scope from 1963.

-==Differences between D56 and D55A==
+==Internals==
+===Differences between D56 and D55A===
 The main differences between D56 and D55A are the following:
 * Both have 15 MHz Bandwidth.
 * 10 mV/div compared to 100 mV/div Sensitivity.
-* Circuit Boards are used more consistently apart from the Vertical Amplifiers.
+* Circuit boards are used more consistently apart from the vertical amplifiers.
-* Mixed Transistors and Tubes. Still many tubes, but adding transistors gives more possibilities.
