Excellent working and cosmetic condition. Please check the pics, you get exactly what you see. Pictures are part of the description of the cosmetic condition. Including protrusions, the tuner occupies 19 × 14 × 3. You can remove the handles for rack mounting, but the hole spacing is nonstandard. The tuner weighs 11¼ lbs and consumes 15 W. The display is vacuum fluorescent and all controls are pushbuttons. 13 memories store frequency and mode. An F-connector provides 75 antenna input. The RF amplifier and mixer use dual-gate MOSFETs. A single tuned circuit before the RF amp and three that follow yield a flat RF passband when sweep-aligned. Although the front-end uses AGC, it easily overloads. The wide IF uses a pair of Murata SFE10.7MX-A 250 kHz ceramic filters and two adjustable IF transformers. Narrow cascades three SFE10.7MZ1-A 180s and another transformer with the wides. All filters are the blue, low-group-delay type. An LA1235 IF amplifier / quadrature detector feeds an LA3401 stereo decoder, which uses a ceramic resonator and no oscillator trimpot. Unbuffered LC ultrasonic filters drive the audio output, which high-voltage 4966 CMOS switches route. Series/shunt JFETs provide muting. Back-to-back Zeners protect the output circuitry. A 5 × 2 loop antenna has an inductance of 13 µH and a Q of 74 at 1000 kHz. It drives a fix-tuned RF transformer. A switchable RF attenuator made from a resistive optoisolator feeds a JFET/bipolar cascode RF amplifier. A double-tuned circuit precedes the mixer. The 450 kHz IF has two bandwidths. The frequency response extends to 15 kHz in wide. The tuner was designed before FCC rules limited audio to 10 kHz. Response is 3 dB down at 5.7 kHz in narrow. An audio equalizer flattens the response. A 10 kHz notch filter kills adjacent-channel heterodynes, while a 25 Hz stereo pilot canceller enables deep bass response. The controller/PLL is a Toshiba TC9147BP. A switch on the main PCB selects 50 or 75 µs deemphasis. A jumper in the power supply permits 110 or 220 V operation. The supply uses three-terminal regulators. The item “CARVER TX-11b AM/FM QUARTZ SYNTHESIZED STEREO TUNER RARE EXCELLENT CONDITION” is in sale since Sunday, June 6, 2021.
