The Model 774 Type 4 is a combination Analyzer and Tube Checker, a part of the I-56-E Test Set. The device is designed to operate on voltages between 105 and 125, at a frequency of 50 or 60 cycles.

This model provides three separate functions for testing receiver performance.

The analyzer section consists of A.C. and D.C. voltage, ohmmeter and capacity ranges, and will provide all measurements needed for the proper servicing of a receiver.

Built into the panel is a socket selector block which, along with the adapters, will facilitate the measurements of voltages and current from the top of the receiver.

The tube checker is the regular Weston Emission Tube Checker, arranged with the necessary features to check all tubes within the scope of a portable device.

The Model 774 is built on a 50 mill steel panel with the sockets, rotary switches, and toggle switches positioned in a neat and orderly fashion.

The upper right hand portion of the panel contains the socket selector analyzer.

The meter used in the Model 774 is a standard 100 microampere instrument.

A wooden case houses the completed instrument with a compartment at the top to hold the adapter block and the necessary test cables for the device.
