This preamp is reference the famous Matisse preamp Circuit , using High voltage 400V power supply, parallel Tubes, the first stage is 12AX7 and the second stage is 12AT7. this much better than most other lower voltage Matisse preamp Clone Circuit.


PRT06B preamp design thinking:

1: It is consistent with the 400V power supply voltage of the original machine.
2: All voltage parameters are consistent with the original machine.
3: DC filament power supply to avoid the influence of voltage fluctuation on the filament
4:The output signal is switched on with time delay to avoid the strange sound generated by the electron tube when the engine is hot


This preamp sound is very comprehensive and dynamic. The human voice is natural
and delicate, the strings are smooth, stretched, and the positioning and imaging are excellent. The high and low frequencies are extended in place, and the low frequencies dive deep and powerful without lack of  flexibility.

There are many tube preamp on the Internet design is not very reasonable. The main manifestation is that the distance between the Tubesis too close. ZERO-ZONE suggests that the distance between the center
of each is greater than 40mm.
