Accuphase T-11
The Accuphase T-11 is a premium FM stereo tuner renowned for its precise engineering and outstanding build quality. Its advanced circuitry, refined construction, and excellent sound quality have made it highly regarded among audiophiles and vintage audio collectors.
The frontend uses a double-tuned RF stage, while the IF mixer is based on a push-pull MOSFET configuration. The IF section supports a Narrow mode, allowing better rejection of adjacent-channel interference. A signal meter can display multipath reception, helping optimize antenna positioning for the best possible reception.
For long-term reception stability, a PLL-based circuit is used to lock the tuner oscillator by synchronizing it with the 38kHz subcarrier signal contained in the FM broadcast.
The T-11 supports remote control operation and offers 16 FM station memory presets. Additional features include balanced audio outputs and adjustable output level control.
