The Telequipment D56 is a 15 MHz dual-channel dual beam oscilloscope 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 D55A, which is an all-tube scope from 1963.

Internals
Differences between D56 and D55A
The main differences between D56 and D55A are the following:
- Both have 15 MHz Bandwidth. However, at 10 mV/div sensitivity, the bandwidth is limited to 500 kHz.
- 10 mV/div compared to 100 mV/div Sensitivity.
- Circuit boards are used more consistently apart from the vertical amplifiers.
- Mixed transistors and tubes. Still many tubes, but adding transistors gives more possibilities.
Tubes
- 35 tubes + CRT (same CRT as in the D55A).
- Vertical Amplifiers (each): 2×EF184, 2×ECC88, 2×E810F.
- Horizontal Amplifiers (each): V101: ECF80, V102 ECF80, V103: ECC88, V104: ECC88, V105: EAA91, V106: ECF80, V107: ECF80, V108: ECF80, V109: ECF80.
- Time Delay: V302: ECC88, V303: ECC88.
- Trace Blanking: V304: ECC88, V305: ECC88, V403: EF184.
- Regulators Board ? PC23: V301: ECC88.
- Regulators Board PC24: V401: EL86, V402: ECF80.
- CRT: 5" flat-face, double gun, P1 phosphor. 1374K G.E.C.
Transistors
- Nine germanium PNP transistors.
- Motorola LB293, T-119, TO-92, germanium, PNP: TR251, TR252, A; TR101, TR102, B; TR101, TR102. 6 pcs. total.
- Newmarket NKT452, TO-3, germanium, PNP, 3A. TR402.
- Newmarket ACY22, TO-5, Germanium, PNP. 225mW, TR401, TR403. 2 pcs.
