The Tektronix 310 is a compact portable oscilloscope introduced in 1955. It is a 4MHz single-trace, single-timebase scope with a 3" (7.5cm) round CRT. The 310 is a tube scope and uses 175 watts, but it does not have a fan. So it tends to run hot, particularly when used in a hot environment with still air. It has a 165 degree Fahrenheit 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 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. There is also a revised version, the 310A, introduced in 1959. The 310 uses printed-circuit boards but the 310A returned to ceramic strip construction. P2 phosphor was standard. P1, P7 and P11 were also available.

Is this the only time that a Tek design was moved from PCB back to ceramic strip?
