The Tektronix 7704 is a four-bay mainframe introduced in August 1969 that takes two 7000-series vertical plug-ins and two 7000-series horizontal plug-ins. The rated bandwidth is 150MHz. The 7704 was followed by the 7704A.
The 7704 uses a switchmode power supply (SMPS). The CRT power supply is separate from the low voltage power supply. The 7704 SMPS is all discrete.
