PRT06B Kits Fever Tube Preamplifier PRE Bile Preamp  Board Reference Matisse


PRT06B design thinking:
It is consistent with the 400V power supply voltage of the original machine.
The voltage parameters are the same as the original machine.
DC filament power supply, avoiding the influence of voltage fluctuation on the filament

With a delay to turn on the output signal to avoid the strange sound generated by the tube when it is in the heat engine

Listening Feelings:
The test uses Twilight's 12AX7+12AT7 (also measured 12AX7), the most special in the low frequency, the depth of the dive, the strength, the bounce is unmatched by many stone preamps, when using the imported tube EN foot test, the details are more Rich, quieter and more mellow.

Parameters:
PCB size: 150*200*1.6MM FR4 A grade plate
Power supply requirements: 0-300VAC*40mA, 0-14VAC@1A
