Summary

[edit]
Description
English: The Little Dot Micro-Tube is a hybrid headphone amplifier, which combines the natural timnre of vacuum tubes to the detail and low distortion of solid-state amplification.

The Little Dot Micro-Tube employs the miniature 6N16B-Q military tubes in a "SRPP" circuit design for very low distortion and excellent National Semicond uctor operational amplifier LM4562. This new op-amp has exceptional performacnce in high fidelity audio applications and has distortion of less than 0.000003%. The solid-state middle stage consisiting of the LM4562 and Transistor buffer composes a closed amplification loop, which ensures tight regulation and translates into detailed, non-harsh treble and dynamic bass even at high volumes

To protect the headphone from any possible harm,the Micro-Tube employs a sonically transparent intergrated upc1237A circuit, which will shunt off any anomalous over-voltage.
