PIONEER TX-8800
¥44,500 (around 1975)
An AM/FM stereo tuner that inherits the TX 8900 technology and aims for high performance beyond the class.
The front-end section uses a four row frequency linear varicon, and for high-frequency amplification, low-noise, high-linearity FET is used to improve sensitivity and interference rejection capability.
In the IF stage, selectivity characteristics are improved by making the 2-element ceramic filter with excellent phase characteristics into a 3-stage configuration.
The IC incorporates more than 200 elements in total into a single IC, with five stage limiters to adjust the waveform and improve various characteristics.
A PLL circuit is used in the MPX section.
Stable separation is obtained by exclusive high integration IC of the PLL circuit.
A muting circuit using a relay is built in to eliminate noise between stations at the time of detuning.
The AM tuner section uses a two row varicon and high-integration IC to enable stable reception regardless of wave strength. The IF stage uses a ceramic filter to obtain sharp selectivity characteristics.
It is equipped with an MPX noise filter to cancel high-frequency noise that is likely to occur when receiving stereo signals in weak electrical power regions.
Equipped with a signal meter.
Equipped with two output terminals, fixed and variable.
It also has multi-path outputs and four chMPX outputs.
The scale faces are lit using the reflect lighting method.
