Lite Audio LS9 JADIS Circuit preamp valve 12AX7 Pre-amplifier With Remote
This preamp is base on famous JADIS Circuit, Enlarged part with a three signal amplifier, each stage uses two 12AX7, a total of six 12AX7. Power supply using 6Z4 rectifier, 12B4A adjustment, 12AT7 voltage comparator. Signal amplification part of all imports of Russia's new tube EH. Power part of the 6Z4 is the dawn of a license, 12B4A imported second-hand tube, 12AT7 once again using the EH tubes imported from Russia.
The remote preamp are using VOLUME CS3310 conrtol board.
LS9D tube regulator board, ARC tube voltage lines. 6Z4 rectifier, 12AT7 for voltage comparator, 12B4A to make adjustments, the voltage from 150V ~ 400V adjustable, with two filament regulator can output 6.3V or 12.6V voltage (in need of replacement components)
