Fever gall preamp circuit board is a principle of imitation crew Musical Fidelity X-10D design, to be rational optimization, performance is more stable than the new machine, tube play to improve ten percent.
Power works: a turn on the power tube filament heating is started, when the boost voltage starts from zero boost, and other hot filament tube, and also happens to boost boost finished, so this is the same with bile rectifier, 8 470UF capacitor filter is very clean, good power supply system will not have a hum, the filament is 12V DC power supply requires two filament tube is connected in series with a DC filament also to reduce noise.
