The Millen No. 90651-A Grid Dip Meter features a transistor d.c. amplifier, and taut band meter.
The No. 90651-A has a transistor d.c. amplifier to increase sensitivity. It provides full scale meter reading at all frequencies from 1.7 to 300 mc. It has a modern, taut band meter to eliminate any possibility of the meter ever becoming “sticky.” These additions are made while still maintaining all of the features which have made the Millen No. 90651 Grid Dip Meter so thoroughly reliable it has become the standard of the industry. It uses the same stable oscillator .without spurious dips, it has a transformer-type power supply, it has seven coils protected by form fitting molded covers, etc.
