The 310 is a tube scope and uses 175 watts, but it does not have a fan. Therefore, it tends to run hot, particularly when used in a hot environment with still air. It has a 165 °F (74 °C) [[thermal cutoff]] switch in series with the primary of the power transformer. For extended use in one place, a tilted fan base, the FB310 (part number 016-012) was available. The fan base blows air upward through the perforated bottom panel of the 310. | The 310 is a tube scope and uses 175 watts, but it does not have a fan.

The 310 is hinged at the rear, allowing reasonably convenient access to the circuitry despite the fact that the components are packed more densely than in other Tektronix scopes of the era. | The 310 is hinged at the rear, allowing reasonably convenient access to the circuitry despite the fact that the components are packed more densely than in other Tektronix scopes of the era. | ||
