JINRO SHOCHU Congratulations on your purchase of the Audio Note (UK) JINRO Shochu Stereo Power Amplifier. It is a Pure Class A Singled Ended valve amplifier that uses the highly regarded 211 triode valve, producing a level of performance that is radically superior to the vast majority of current designs.
UNPACKING AND INSTALLATION Please take care when unpacking your JINRO Shochu Stereo Power Amplifier. Choose a clean, clear location to unpack your unit. Be aware that the amplifier is very heavy; before attempting to unpack or lift the unit, check the weight and if necessary use more than one person so that it can be moved safely and easily. We recommend that you retain and carefully store all of the original packing materials, in case transportation / shipping is required at a later date.
VALVE INSTALLATION The amplifier is shipped without the valves installed. It is necessary to install the valves before the amplifier can be operated. It is essential that the valves are installed correctly or serious damage that is not covered by the warranty will result. We recommend that your dealer perform this procedure for you if you are in any way unsure. FIRSTLY, ENSURE THAT THE AMPLIFIER IS NOT CONNECTED TO A MAINS ELECTRICAL SUPPLY, AND THAT THE POWER CORD IS NOT CONNECTED TO THE AMPLIFIER.
VALVE INSTALLATION continued… Inspect a 211 valve and you will notice that there is a small ‘pin’ protruding from one side of the valve base; this locating pin ensures that the valve can only be correctly inserted into the amplifier in one way. Also examine the two large apertures in the top plate of the amplifier, located between the two small valves and the black rectangular transformer covers. These are the insertion points for the 211 valves.
VALVE INSTALLATION continued… Looking from the back of the amplifier, insert the 5R4WGB valves into the two empty sockets located on the left, situated between the black rectangular transformer covers and the loudspeaker connection binding posts. Locate the rib on the central pin of the valve and align with the valve base (it can only be inserted one way due to this locating rib) and with gentle but firm pressure insert the valve. Finally, insert the two 6V6 signal valves into the front two sockets.
CONNECTION Line inputs Being a stereo power amplifier, the JINRO Shochu is fitted with a pair of XLR / Balanced input sockets. Looking from the front of the amplifier, they are located towards the front of the left hand side panel. Connect the outputs from your preamplifier to these inputs. Ground Post A ground post is provided for connection to those source components that also use a separate ground terminal.

OPERATION Once all the connections are completed and checked, ensure that the volume control of your preamplifier / source is at the minimum setting. Turn on all components in the signal chain before the JINRO Shochu; the power amplifier should always be the LAST component to be switched ON, and the FIRST to be switched OFF. Turn on the amplifier by using the rocker switch located at the top right of the rear panel, just above mains inlet socket (viewing the amplifier form the rear).
