The Tektronix 7704 is a 150 MHz, four-bay mainframe introduced in August 1969 that can take two 7000-series vertical plug-ins and two 7000-series horizontal plug-ins. The 7704 is one of the initial oscilloscopes introducing the 7000-Line and very lavishly build using contacts embedded in the aluminium frame for interconnecting the gold plated PCB boards.

It was superseded by the completely redesigned 7704A in 1973. There is also a rack-mount version, the R7704.

Internals

The 7704 uses an all-discrete switch-mode power supply (SMPS) in resonant half-bridge topology. The CRT voltages and heating are produced in a separate switching stage running off the main SMPS DC output. Logic, channel switching, and readout use the classic TEK 7000 series custom ICs (155-0009-00 to 155-0022-00), the horizontal and vertical amplifiers are completely discrete.
