6J1 fever gall bladder before the board is imitation machine music fax X-10D circuit principle design, to be a reasonable optimization, more stable than the original machine performance, the tube to play increased by 10 percent
This machine uses a single 12V AC input, do not have to worry about looking for high voltage power supply The board comes with a boost you enjoy the low power supply to enjoy the charm of high-voltage tube
A power supply, tube filament began to heat, then boost from the zero voltage began to boost
The filament is DC 12V power supply, the need for two tube filament is in series, the use of DC filament is also to reduce noise.
