FRONT PANEL
ACB
A - BALANCE - This is a special Nobles balance control. Unlike most balance controls, this one has no loss at center (detented) and can be considered to be a straight wire if it is in the 12:00 position. It only reduces the volume of one channel at a time
.
B - VOLUME - This is also a high quality Nobles conductive plastic precision attenuator.
C - BACKLIT PANEL - This is the power indicator. If the IEC mains is properly connected and the On/Off Switch is "ON" and this panel does not glow then you probably have a blown fuse. It is located as part of the IEC socket assembly. If it does not glow but the tubes do and you have music then the little bulb is dead. It can be replaced easily. See the drawing below.
The lamp looks just like a fuse .Do NOT put a fuse here. Replace it with a 12 volt, 0.15 amp, 1/4 X 1 1/4 lamp. It pulls straight up if the Stingray is upside down but you may need a hook or

E - POWER SWITCH
F - IEC MAINS SOCKET. This is where the power cable goes. Note that your amp should be wired correctly for your country. You may want to check the packing box to be sure. Also notice that this is a grounded 3 pin cable. If you get a hum problem, see the previous page for some simple troubleshooting hints.
