Master 
 

The Master controls the overall output level of the 2

nd

 channel. When the tube-buffered loop is 

engaged, it acts as the output level 

before 

the signal is sent to the effects processor(s). If you do 

not have the effects loop engaged, the Master acts as the overall volume level for the 2

nd

 channel. 

 
 

BACK PANEL  
 
A/C Plug 
 

Plug your amp’s power cord in here first, then to the wall.  
 

On/Off Switch 
 

This switch turns the amp on or off. Please make sure that the Standby Switch is in the Standby 
mode before turning that amp on and off. This will help increase the life of the power tubes. 
 

Standby Switch 
 

Leave this switch off when turning on the amp and let the amp warm up for a full minute before 
turning this switch on. It’s best to let tubes warm up before playing. Also, turn the Standby 
switch to Standby when you will not be playing for a while (for example, breaks in between sets 
of your performances, etc.). 
 

High Tension Fuse – 100R 
 

High Tension is just another way of saying High Voltage. Voltages at this point can be anywhere 
from 350-500 volts depending on the model so it is always a good idea to make sure the amp is 
“off” when installing or removing the fuse. Do not stick anything inside the fuse holder other 
than a fuse. Do not attempt to defeat the fuse with a metallic gum wrapper or nail. This fuse is in 
series with the output transformer. Its function is to prevent collateral damage to the amplifier in 
the amplifier in the even of tube failure. If you replace the tubes and the fuse blows again, seek 
qualified technical help.   

 
Solid State or Tube Rectifier Selection 
 

This feature allows you to select between a tight and punchy solid-state rectifier or a spongy and 
sweet tube rectifier. More of a function in setting that tactile response of the amp to taste, this 
feature further extends the range of the Hot Cat amplifier. If you want a more modern and 
punchy tone and feel, select the solid-state rectifier. If you need more “sag” and “bloom”, select 
the tube rectifier.
