This is a low noise 12AU7 double triode valve equivalent to Mullard / British type ECC82 valves and ideal for lower gain/gainless stages in guitar and other audio amplifiers. Manufactured by Shuguang, the same brand as fitted by Marshall in many of their amplifiers. An ideal replacement for standard 12AU7 (ECC82) valves in guitar amplifiers or other audio amps, or for use in DIY build guitar amplifiers. Sent by First Class post for fast delivery. Changing your valveOnce you have the back or cover removed from the amplifier/radio/record player you are changing a valve in it's easy to change. First, the safety warnings;, Unplug the unit from the mains before removing any covers. Don't try to change the valve when the unit has been recently switched on. . . valves get hot enough to burn you! Try not to touch anything inside the unit except the valve you are changing as some parts can hold high voltages even when it has been switched off for some time. Now for the easy bit. . . . hold the valve you are changing between two fingers and your thumb and rocking it slightly to free its pins, pull it firmly straight up and it will unplug. You will see that the pins form a circle with a gap in it where there is no pin. Take a look at the socket to see where the gap with no pin socket is and taking the new valve, line it up correctly with the gap and again rocking it around slightly (only a few degrees) push the new valve in until it is firmly seated. Replace back cover, switch on. . . . all done! Preamp valves like this double triode don't need any further setting up or baising, so thats all there is to it. Changing these valves can make your sound instantly brighter and punchy, so why not spend a few pounds and bring the life back into your amplifier!
