G&W TW-Z1.0B Germanium Preamplifier Hifi Preamp Refers to Single-Ended Preamp for Naim NAC42.5

G&W TW-Z1.0B Germanium Preamplifier Hifi Preamp Refers to Single-Ended Preamp for Naim NAC42.5

Features:
- Germanium semiconductor triodes are used
- Refers to single-ended preamplifier for Naim NAC42.5
- The use of high-frequency germanium semiconductor triode as a single-tube input circuit well reduces distortion and controls noise, improving the signal-to-noise ratio. It broadens the frequency response to more than 50KHz
- Chinese 3AX31 germanium semiconductor triode is used as a common-emitting voltage amplifier circuit to make the sound rich in overtones and delicate and dynamic
- 3AX54C germanium semiconductor triode is used as the single-ended emitter output. The net state current of each transistor is larger to improve the dynamic range
- Red original 6.8uF 50V film capacitor (for WIMA) is used as coupling output, which makes the sound flavor extremely outstanding
- Adopts Japan ALPS16 type plastic potentiometer to control the volume
- 4pcs 25V 4700uF audiophile grade electrolytic capacitors (for Panasonic and other brands) are used as main filter capacitors. Original 100uF 40VDC electrolytic capacitor (for Sweden Rifa) is used to maintain the continuity of the current
- 75mm thick copper thin double-sided printed circuit board
- Solid silver aluminum alloy knob to control the volume
- Its shell is made of all aluminum alloy profiles. 8mm thick black aluminum alloy side panels with grooves, and silver aluminum alloy brushed panels at the front and back. The front and back panels and the top cover are free of mounting screws, and the black aluminum alloy brushed top cover has the trademark "G&W" engraved by CNC machining center
- Audiophile grade EI transformer with quality iron core and epoxy can seal without any noise
- Input RCA socket adopts thick gold-plated products from Taiwan. 718 military resistors are used
