543
The Tektronix Type 543 is an all-tube 30MHz scope introduced in 1958. It takes letter-series and 1-series plug-ins. It is similar to a 545, but without the second, delayed timebase. Instead, it has a range of horizontal magnifiers from X2 to X100. It has the same six-stage balanced distributed amplifier (twelve 6DK6 tubes) as the 545. While the 545 has two non-calibrated X-input sensitivities, the 543 has an X-input with three calibrated selectable deflection sensitivities: 0.1V/cm, 1V/cm, and 10V/cm.
The standard CRT for the 543 is the T65 with P2 phosphor, part number 154-175. The standard CRT for the 543B is part number 154-0478-00, also known as the T5470-31-2.
The total acceleration voltage on the CRT is 10kV. The CRT power supply uses five 5642 HV tube diodes.
543B is a hybrid and vertical delay line have no 6DK6 and LC but 186 ohms delay line.
