Description
Here we have a General Radio Co. 1230-A D-C Amplifier and Electrometer. The serial number is 641.
It measures 7 1/2" wide x 8 1/4" deep (including knobs and connectors on the back) x 13" tall (including the handle).
From there catalogue at the time "The General Radio Company manufactures a variety of laboratory amplifiers, which range from general-purpose, wide-range instruments to units specialized to perform a particular group of functions. Many of the needs for amplification which arise in measurements in research, engineering, and industry can be met with one of these instruments. The following amplifiers are described in this section: The TYPE 1230-A D-C Amplifier and Electrometer is a new instrument replacing the well-known TYPE 715-A Direct-Current Amplifier. It is basically a millivoltmeter with an extremely high input resistance. It is also arranged to be used very conveniently as a micro-microammeter and mega-megohm meter'. Because of these features, together with its high sensitivity and excellent stability, this new instrument has a wide range of applications in d-c measurements."
The condition of this unit is amazing, with it looking virtually brand new. I plugged it in using an extension cord and it powers up, beyond that it is untested and sold as is.
