build guide

The UralTone All Octal SE Stereo amplifier is a traditional Single Ended stereo amplifier with one exception. It operates on a 12VDC (7A) power supply, so there is no 230VAC network input or transformer within the amplifier itself, making assembly safer for beginners. Inside the chassis, there are two boost regulator-type power supplies that elevate the incoming 12V voltage to about 300V, enabling the tubes to operate at optimal voltage and current levels.
