Features of this machine's circuit
1. Use the latest and improved export-installed famous tube 6CA7T for strong power amplification and VU meter for volume indication
2. Choose the best super linear push-pull power amplifier circuit to make the low frequency driving force sufficient and the sound rich.
3. Pre amplifier is an SRPP amplifier circuit and a "long-tail" inverter circuit, which makes the machine have a wide frequency response and low distortion.
4. The output transformer is made of special silicon steel sheet (0.35mm thick) imported from Japan for audio, high-strength oxygen-free copper enameled wire and special multi-layer layered grouping winding technology.
5. This machine is all made of non-polar Philips (MKP) capacitors and high-quality gold resistors made of special hair-wound electrolytic capacitors for audio from famous foreign manufacturers. The upper channel uses imported special large-scale volume potentiometers.
6. The VU meter is used as a volume indication, which can reflect the volume in a professional and accurate manner.
