The conventional type of vacuum tube voltmeter has been found to be unsatisfactory when used to check amplifiers designed to reproduce e.m.f's whose fundamental frequencies range from a few to 100 cycles per second. These difficulties can be overcome by the use of a symmetrical tube circuit which integrates the two halves of the input wave to produce a smoothed direct current component. Certain other advantages which result from the use of the same circuit are reported. The choice of Type 31 tubes makes the use of an inexpensive plate current meter possible.
