MUZISHARE R90 Electronic Tube Preamplifier HiFi Power Amplifier with VU Meter Support Frequency Adjustment

MUZISHARE R90 Electronic Tube Preamplifier HiFi Power Amplifier with VU Meter Support Frequency Adjustment

Features:
- A power supply transformer made of Z11 iron core with high-end special technology and special material fusion.
- The front-end main circuit uses two 12AX7 vacuum tubes and four 6KE8 vacuum tubes.
- The PHONO circuit uses two 6KE8 vacuum tubes and a RIAA circuit to achieve MC/MM functionality.
- High voltage power supply uses a 17BE3 vacuum tube as the rectifier and a 12DT5 vacuum tube as the voltage regulator circuit.
- Fixed high and low frequency point enhancement selection function, with added direct selection switch.
- Six sets of signal inputs (MC-H, MC-L, MM, CD, AUX, BALANCE).
- This machine has specially added two sets of RCA outputs and one set of balanced output functions.
- Power on high voltage delay and mute delay function (approximately 30 seconds).
- Adopting for ALPS high-end potentiometer.
- Peripheral output level indicator function.
- The sound is soft, pure, and smooth, suitable for appreciating various types of music.
