The Telequipment S51 is a low-cost single-channel 3 MHz scope originally intended for the service and education markets.

There was an S51E model variant for education that eliminated the external trigger input in favour of a sweep (sawtooth) output, and an S51T variant with an additional (selectable) horizontal preamplifier (100 mV/cm at 10 kHz bandwidth).

It contains 7 tubes except the CRT (one ECF80, six ECC88) and one transistor.

The S51 is convection cooled.
