Great workbench AC VTVM and audio/RF preamp for use with 'scope!
This AC voltmeter, in addition to having wide bandwidth and a switchable 100 kHz low-pass filter, is a great workbench adjustable preamp. Need more 'scope sensitivity? Just connect this unit to the device under test and connect your 'scope to the rear panel output banana jacks for a nominal 1 volt output. Also works as an audio preamp for use as a signal tracer. Note: after many years the switch contacts do get oxidized. A quick shot of a safe-for-plastics contact cleaner was all it took to bring this one immediately back to perfect functioning. Highly recommended ! Mike/
