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 also features the 7000-series remote control connector on the rear panel.

It was superseded by the completely redesigned 7704A in 1973.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.
