                                                    CONTROLS  
       PRE-AMP 

         

 

         INPUT 

 

         Jack plug input connection for your electric guitar. 
         High impedance input connection for instruments. 

         

 

 

        VOLUME 

         Adjusts the gain of the pre-amp and is used to set the  
         overall volume of the amplifier. 
         The volume control also acts as a switch, when pulled the switch 
          defeats the tone circuit. This adds middle and gain. 
 

        PULL EQ CUT 

 

        This is a bypass for the tone controls (tone stack). The tone controls do not operate                                       
        and you will find a large increase in gain. 
     

 

 

         TREBLE 

         The treble control increases the high frequency response. 
 
         

BASS 

         

The bass control increases the low frequency response. 

        

 

        

 EDGE 

         

The Edge control adds extra bite to the tone. 

      
        

OUTPUT STAGE

 

         

        

OUTPUT SWITCH

 

       

This switch alters the output power:  Position A=7 Watts,  

         position B=1 Watt, position C=1/4 Watt position D=1/8 Watt 
         Note that, unless the volume is adjusted above the power 
         selected, you will not notice any change in output level.  

         

 

        

OUTPUT 

        The output jack socket is connected to an 8 Ohm internal 
        speaker. 

 

         MAINS INDICATOR 

         When illuminated, there is power to the amplifier. 

 

         

MAINS FUSE

 

         The fuse holder contains the mains fuse for the amplifier.  The  
         mains fuse protects the amplifier from electrical faults. 

 

         

HT FUSE  

(located on the speaker side of the chassis)  

 

          Protects the output valve. 

 
 
 
 

         

Replace a failed fuse only with the same type and rating.
