2. Doug and looked for are amps that sound good no matter where the knobs are It is a rare quality that we insisted on hope this hand crafted amplifier gives you years of enjoyment musical results and pride in ownership appreciate your confidence Using your PRS Amplifier IMPORTANT Before using your amplifier refer to the IMPORTANT SAFETY INSTRUCTIONS insert supplied with the product Powering Up Make sure your speaker cabinet is connected to the correct speaker output impedance jack with a high quality speaker cable Do not use guitar cords 2 Make sure the power cord is connected to the correct grounded outlet 3 Make sure there is at Least 6 inches of clearance behind the amplifier to allow for proper cooling Never place the amplifier against a wall or other equipment and keep it clear of other heat sources such as other amplifiers or stoves Make sure there are no flammable items such as curtains behind the amp Do not drape items over the amps that can prevent proper cooling Do not set drinks or other liquids on top of the amp that can spill into the amp 4 To increase the life of the tubes set the Standby switch to the STANDBY position before powering on Turn the POWER switch on and let the amplifier warm up for 2 minutes before setting the standby switch to ON If this is the first time you are turning on the amp check to see if all of the tubes are glowing 5 Plug in the guitar cable turn the v

5. ever force tubes into the sockets if there becomes a problem Also never torque the tubes only gently rock them from side to side during insertion or removal After preamp tube installation place the cylindrical spring tension preamp tube covers over the tubes Ensure the cooling fan is plugged back into the jack on the chassis Failing to do so can create a safety hazard Replacing preamp tubes will not require any adjustment but the power tubes will need rebiasing to assure proper operation After power tube replacement initially inspect the tubes often to assure there are no cherry red components within the tube Tubes today can have a wide variety of tolerances and a re bias is highly recommended with new ones Fuses There are 5 fuses installed in the amplifier Only of these the main input fuse is accessible and replaceable by the user There are 4 fuses internally for added safety 2 of these fuses are high voltage fuses and 2 fuses are for the lower filament voltages In all cases labels indicate the type and rating of the fuse Replacement fuses MUST BE THE SAME TYPE AND RATING If they are not you can permanently damage your amplifier Please contact your Local PRS dealer or the PRS accessories web site for information on ordering replacement fuses Instructions for Qualified Service Technician Replacement of internal fuses requires removal of the back panel and removal of the chassis First ensure the power cord is not plugged i
6. f handling and most likely about to fail Two other conditions to observe are filaments not glowing or 2 a miniature fireworks display inside the tube Any of the above conditions indicate serious problems with the tube and should be taken care of immediately Tubes quite often are the cause of spurious noise in the amp Microphonic tubes will squeal or rattle with the vibrations of the cabinet If suspected tap each tube lightly with a pencil with the amp powered up the suspect tube will let you know Note that there is a normal metallic clinking when doing this but a microphonic tube will be quite loud Instructions for Qualified Service Technician To install the tubes check that the power cord is not plugged in then remove the wooden back panel with a screwdriver and notice the tube sockets Note that the cooling fan may need to be unplugged from the chassis Looking from the back install the Power tubes EL34 6L6 etc in the left sockets In each case align the center pin guide correctly with the socket making sure that the pin guide key fits with the corresponding slot in the socket The I2AX7 and I2AT7 preamp tubes can then be placed in the smaller 9 pin sockets to the right of the power tubes Please refer to the tube chart inside the amplifier for proper pre amp tube locations Be aware of the pin alignment with these as there is only one way they can fit We utilize tube sockets that allow relative ease of tube installation but n

10. u need an amp to play through and have a friend who makes great amps He took me to the booth of a Texas amp builder Doug Sewell Loved the way his amps sounded and after barely saying hello Doug and were inside rewiring the amp was going to play through Since that day Doug and have spent years rewiring and Listening to every single possible variation to finalize the circuits Our goal was to have highly usable and musical amplifiers am not an amp collector am an amplifier user who keeps the amps am presently playing through That said after Doug and got several of the prototypes finalized sold some of my old coveted Live and studio amps because ours sounded considerably better The next step was to take the prototypes to musicians who are known for their amplifier tone as well as their playing What s interesting is that when spoke to these artists about trying the amps they all said the same thing Sure l U use them if love them In a real way amplifiers are musical instruments They are the devices that amplify the sound of the player s hands the guitar and possibly the pedal board They must share many qualities They must work they have to have a beautiful balance of bass midrange and treble the highs should be sweet not harsh they should be easy to operate and be highly musical In addition amps should clean up really well when you turn your guitar down The final quality that
