Specifications:

The FE-6J1-2 tube hot plate preamplifier is the schematic simulation circuit of the Music Fax X-10D design team. For reasonable optimization, the performance is more stable than the machine, and the tube group is increased by 10%. The board uses a single 12V AC input battery, and the processing circuit provides the positive and negative voltage and filament voltage supply voltage required by the 6J1 tube.

Energy plays a role: when the 0 voltage pulse starts to increase the hot filament tube, etc., the open tube that supplies power to the filament is opened, which will also increase the pulse completion rate,. Therefore, this is the same as the very clean filter of the 8 * 470 uF capacitor. A good power supply will not buzz. The filament is a 12 volt DC power supply, and two tubes connected in series with the DC filament are required to reduce noise.


The package includes:

A: Separate board

B: Diy kit parts (without electronic tube)

C:   complete set (parts+2 6ji electronic tubes)

D:   complete set (parts+2 6k4 electronic tubes)

E: A complete set of 6JI+acrylic housing

Note: self assembly is required
