PA-40 Silvery Hood 1969 Golden-sealed Transistor Class A HiFi Rear Stage Power Amplifier 10Wx2

PA-40 Silvery Hood 1969 Golden-sealed Transistor Class A HiFi Rear Stage Power Amplifier 10Wx2

Description:
- Hood 1969 small A-class amplifier, its architecture is not electronic tube, but due to the use of single ended output mode, it has low odd harmonic distortion and operates in A-class state. Although the power is not large, it is used in rooms and with bookshelf boxes, warm and charming, with a strong sense of music and friendly vocals, making it a good choice as a substitute for tube amplifiers.

Features:
- Single ended output circuit, equipped with Class A high static current and active electronic filtering, with a very quiet and dark background.
- CNC all aluminum alloy naturally air-cooled external heat dissipation chassis, laser engraved fonts, not easy to age, not deformed or dropped, high-end aristocratic quality.
- Six gold sealed high-power transistors are used as electronic filters and power outputs, providing a warmer, more delicate, and fuller sound quality than the typical HD1969 that only uses a few small plastic sealed transistors.
- A powerful power reserve is like the engine of a car. A-core breakpoint free transformer, for ELNA AUDIO hifi filter capacitor. Gold filter capacitor for NOVER.
- Regardless of design or testing, multiple instruments are used to repeatedly test and verify the machine's specifications and consistency.
- The Japanese ALPS27 large fully sealed potentiometer has first-class feel, lifespan, and accuracy.
- Large pure copper terminal blocks, which do not turn black after long-term use and have a high output current.
- 4N oxygen free copper signal line for CANARE, with high transmission purity and pure sound quality.
- A large number of imported HiFi capacitors are used, ensuring the sound quality.
- DC protection system: automatically detects the internal circuit condition of the machine, automatically disconnects the connection between the circuit and the speaker, and ensures that the speaker is always working in a safe state.
- Simulated impact delay system: prevents the speaker from being impacted at the moment of startup, and eliminates the popping sound generated by startup.
- Temperature overheat protection system: When the temperature exceeds the safe range, it can automatically reduce the current and output, protecting the overall safety of the machine.
- The input terminals are plated with genuine gold, and the speaker output port is made of pure copper crystal, which is wear-resistant, anti-oxidation, and has a good sound quality.
- High quality volume potentiometer is the most critical core component, which is related to accuracy, feel, and lifespan.
- Double sided gold-plated (genuine gold) PCB ensures lower internal resistance and more efficient current transmission.
