Refer to MATISSE circuit PRT06A 12AX7+12AT7 Stereo tube preamplifier DIY Kit
Introduction:
We have referenced the original MASISSE (high voltage 400V power supply, Parallel tube, The first level is 12AX7, The second level is 12AT7).
1, Relative to the original machine 400V power supply, PRT06A uses DC 280V regulated power supply.
2, The resistance is modified to be equal to half of the current parallel tube current (ie, consistent with the actual single transistor current of the original machine)
3, DC filament power supply, avoiding the influence of voltage fluctuation on the filament
PCB Size: 177mm * 100mm
Power supply requirements:
High voltage: AC 0---220V/40mA
Filament voltage: AC 0---15V/1A
NOTE: This is a Kit, All parts need you welding and test it. (We do not include tubes)
