LUXMAN HQ33
¥ 46,000 (released in July 1963)
Commentary
Stereo tri-amp equipped with FM / Nakanami (AM) / SW tuner.
HQ33 has a configuration in which the variable crossover is omitted from HQ34.
A one touch system with 14 push buttons in 4 blocks is adopted for the operation part, and the operability is improved by using all push buttons.
The tuner section is designed with special emphasis on the sound quality of the FM tuner.
A built-in AFC circuit automatically adjusts the optimum tuning point to prevent tuning deviation over time. In addition, an FM-multiplex connector is mounted on the mounted on the rear for stereo broadcast transmission compatibility.
The tone control is equipped with NF type LUX tone control which is also used for SQ5B and SQ63.
A deep NF circuit is installed in the preamplifier section of the tone control and equalizer to reduce the distortion factor.
The vacuum tube uses a DC ignition system to eliminate ham.
The volume is adjusted separately for the left and right channels.
There is an output meter in the center of the front panel so that you can adjust it while checking the output.
This meter is also designed to operate as a tuning indicator for the tuner by means of a switch.
The exterior case is designed with art bond instead of the commonly used paint finish.
Art Bond is a laminate of vinyl chloride and metal developed by US Rubber Co. of the United States.
