About the TX-11a

The Carver TX-11a is a quartz synthesized stereo tuner known for its advanced noise reduction and asymmetrical charge coupler FM detector technology. It features patented stereo manipulation circuits that improve weak or distorted broadcasts, delivering very listenable signals. The tuner covers FM (87.5 to 108 MHz) and MW (520 to 1710 kHz) bands with digital tuning scale. It offers excellent signal-to-noise ratios of 82dB for FM and 75dB for MW, with a sensitivity of 1.0uV (FM) and 20uV (MW). The AM section provides full low-frequency response without the typical roll-off found in other tuners, and it cancels the 25 Hz stereo pilot tone rather than filtering it. Users praise its noise cancellation and multipath reduction features, which significantly reduce background noise and improve stereo clarity. The unit measures approximately 17.5 x 3.5 x 12.5 inches and weighs about 11.25 lbs. It was marketed around the early 1980s and is regarded as a high-performance tuner with a price around in used markets.
