The device is in very good cosmetic and technical condition. Fully working. All functions work as expected.Ability to work in networks with a voltage of 100-240 Volts. The power amplifier comes in the original box and there is a manual for use.Since the device is over 50 years old, I cannot give a guarantee. Claims are not accepted, returns are not possible.If the buyer wants, I will send a video of how the device works to email or put it on YouTube.I pack very securely, I use two boxes and a lot of styrofoam and bubble wrap.The listing indicates delivery to the EU countries and the UK. To send goods to other regions, it is necessary to clarify the cost of delivery before making a transaction. Kensonic Accuphase P-300CommentaryThe first power amplifier released by Accuphase in the era of Kensonic.It was developed with the aim of an amplifier that can accurately follow subtle changes in music and strong amplitudes.All stages from input to output are directly connected push-pull configuration.Therefore, the bare characteristics before applying NFB (negative feedback) are improved.Six high-output power transistors are used for each channel at the output stage, and these are called triple push-pull.Pure complimentary service direct connection system is adopted for the circuit system.The power supply uses a 40,000 ? Fx2 large-capacity filter and condenser.The parts are tested from the viewpoint of the change of sound quality and durability, and are selected carefully.We have adopted a protective circuit that uses a relay to shut down when a cord short-circuits after the output terminal, a problem occurs in the speaker, or a problem occurs inside the P-300.When an error occurs, the lamp of the power meter blinks to indicate the error.It has a built-in band-pass filter that removes at 18dB/oct. frequencies below 17 Hz and above 24 kHz in order to cut noise components such as unwanted input caused by the rumble of a phono motor or arm resonance in the ultra-low frequency range, and unwanted input in the ultra-high frequency range.It uses a large power meter and can display by switching between 0 db, -10dB, and -20dB range.8 ? load, 150W is scaled as 0 dB.Equipped with a speaker selector switch that can switch between four sets of stereo speakers, and with two selectable inputs.One circuit of the output terminal and one circuit of the input terminal are installed inside the front sub panel.

The company name at that time was Kensonic.The equalizer circuit is fully push-pull driven by direct connection to all stages to improve the bare characteristics before NFB (negative feedback) is applied, making it a high fidelity amplifier circuit.To handle input signals in a wide dynamic range, an A-class drive pure complimentary service is used in the final stage of the equalizer, and a dual plus / minus power supply system ensures a high allowable input voltage.In addition, a low-enhancement circuit is used to enhance the sense of volume when listening to music.An attenuator that can be continuously adjusted by 10 dB is provided to adjust the level of the DISC1 and DISC2 cartridges when you want to lower the level of an extremely high-power cartridge to an appropriate level, or when you want to listen to a comparison of two cartridges using DISC1 and DISC2.In addition, DISC1 is equipped with an input impedance selector switch, which allows you to select between 47k ?, 30k ? and 20k ?.A 25-Hz cutoff subsonic filter is also provided for disc playback.Equipped with independent left and right tone control, the turnover frequency can be switched between 200 hz, 400 hz, 2.5 khz and 5 khz for low and high tones respectively.The change characteristic is ± 10 dB with a 11-contact rotary switch.It is equipped with a low filter of 12dB/oct at 30 Hz or less to cut subsonic noise.It is also equipped with a 5 khz, 12dB/oct high filter to cut hissing from tapes.Tape I/O is installed in the Route 3 so that three tape recorders can be connected.Two of them are capable of dubbing each other. The copy switches are independent, so that it is possible to dub each other while listening to the source.A dedicated amplifier directly connected to pure complimentary service is installed for the headphone to improve the sound quality of the headphone.All amplification stages are supplied from a power supply with a completely constant voltage to improve stability.The speaker selector switch on the front panel allows you to switch the speaker system using a special relay box (sold separately) when the power amplifier is set out of reach.
