Thank you for purchasing your new Splawn amplifier. We have put together a little information that will help you understand the amp and all of its functions. All of our amps are built in our shop in Dallas NC right here in the USA. We build all of our speaker cabs and head boxes in house. Some parts of the amplifier are out sourced such as the chassis's, circuit boards and transformers. The transformers are custom wound by Heyboer and are also made in the USA. We hope that this amplifier will give you years of tonal pleasure.

After unpacking your new amp, Turn the amp around so the back faces you. Remove the four screws to

remove the back cover of the amp. You will find the tubes packaged tightly on the left side of the Amp.

Carefully remove the package and remove the tubes. You will have three preamp tubes and four power

Un-box the Power section tubes. Keep the boxes!! They are marked with tube ratings! You will see on the

base of the tube there is a “key” guide to align the tube into the socket. Starting with the tube socket on the

the tube into the socket until the base of the tube is flush with the Socket. Insert these tubes into the tube

sockets. The tubes are matched so you may install them in no particular order. After you install a tube carefully hold the tube spring retainer and stretch it over the top of the tube and center it. These are light metal and can bend. If you happen to bend them you can shape it to the tube while its installed. Reinstall

Please Check the Voltage selector on the back for proper Voltage selection! Please check the volume

control levels on all channels before powering on. After you plug in the amplifier, Flip the power switch

down to turn on. Wait for a minute for the tubes to warm, then turn on the Standby switch. The Amp is ready
