SPECIFICATIONS

This product is purely handmade, with the circuit designed based on the circuit of a well-known foreign brand's turntable. It simulates the sound quality of a good turntable, with a full, loose, thick, and gentle listening experience

Standard version: Following the original machine's circuit parameters and transistor models (discontinued, limited quantity)
Trial version: The circuit is the same as the standard version, using transistors with performance close to the original transistor parameters

The two biggest features of this product are:
1: Using direct-plug audio dedicated transistors. The transistors used in this operational amplifier module are from the golden era of the audio industry, not the industrial SMD chips of today. Old audiophiles know this!
2: Hand-selected transistors: After hand selection, it relies entirely on the transistor's own consistency to ensure the output mid-level (which experienced enthusiasts know is important), rather than using popular electronic slot machines to artificially change circuit parameters to control output levels




Specifications:
Operating Voltage: ±10V ±18V
Output current: 150MA
Output voltage: ±10mV
Input impedance: 1M

Attached: The experience of a senior enthusiast who has used this operational amplifier
The turntable has a captivating effect, especially the tape playback sound; it's full-bodied, loose, thick, gentle, and durable to listen to The amplifier circuit used in this operational amplifier has been redesigned and modified, incorporating the essence of the amplifier section, improving compatibility, and performing quite well in terms of frequency response and stability Used at his place twice 1794 The performance exhibits a unique heavy feel and musical charm akin to tape, with clarity close to vinyl and stronger emotional expression than CD Or digital broadcast, it's much stronger compared to ordinary gold-sealed operational amplifiers The sound travels quickly, and the output sound is very clean and clear without any blur or distortion It's very natural and can accurately reproduce audio signals without excessive subjective coloration In terms of sound field performance, it has great detail and delicacy, with good separation and layering Bass and midrange have warmth, softness, emotionality, and expressiveness
