AI-assisted summary
Description from the seller
Marantz 115b tuner, produced in the early 70s, is a tuner of great precision for channel reception. Traditional gyro tuning.
The muting circuit consists of a noise amplifier with two transistors and a switching circuit with two transistors and an FET. Control is via three types of inputs: the first is based on signal strength, the second on the noise level in the detector, and the third on the DC component of the detector output. The combination of these three factors not only eliminates noise between stations, but also unwanted signals generated in the tuning range.
The FM front-end section uses a dual-tuning system with a four-gang varicon and a two-stage FET configuration.
Possibility for quadraphonic transmission connections
Aesthetically in good condition, some light signs on the cover as seen in photo, perfectly functional.
