AV-2 AC VTVM

Makes possible sensitive AC measurements required by labs, audiophiles, experimenters.
Particularly useful for hum investigations. Sensitive null detection, phono pickup output
measurements, frequency response runs, gain measurements, ripple voltage checks, etc.
Low level measurements easy because of 1-knob operation and complete voltage coverage.
Large 200-microampere meter (Simpson) has clearly marked and easily read scales.
Ten voltage ranges from 0.01-v RMS to 300-v RMS full scale.
Frequency response plus or minus 1 db from 20 Hz to 50,000 Hz.
Meterbridge circuit has 4 germanium diodes for stability and good linearity.
Styled to be companion piece for the V-6 VTVM and the new AW-1 audio wattmeter.
