AC CORD — Your amp is either wired for 120 VAC or 220-240 VAC. It is possible to rewire for either voltage. 
Contact factory for directions.  WARNING!! Only a qualified technician should ever attempt this or any 
other se rvice requiring the chassis to be removed from the cabinet!  
 
FUSE — Use fast-blo 4 Amp for 120 VAC or fast-blo 2 Amp for 220-240 VAC.  
 
SPEAKERS — Output for speakers. Be sure not to load the amplifier with less than 4 ohms minimum imped-
ance. Operation with less than 4 ohms will eventually cause failure due to overheating.  
 
VENT SLOTS — It is imperative that this amp receives adequate ventilation. Your MosValve power section nor-
mally produces more heat than typical solid-state circuits. Treat your investment right  
— LET IT BREATHE! 
 
EFFECTS LOOP — This system provides ultimate flexibility and control for your effects, regardless of type. See 
the section entitled. "How to properly use the Effects Loop" for further description.  
 
FOOTSWITCH — The two footswitch jacks are provided for switching Channel, Reverb and Stack.  Jack #1 is 
for Reverb and Channel switching. Jack #2 is for Stack and Channel switching. The footswitch supplied will 
switch either combination of these functions depending on which jack is used.  We decided to offer a 2-switch 
footswitch and stick with a common stereo 1/4” jack rather than going to a less common connector and a 3-
switch footswitch. This was for three reasons. First, a 3- button footswitch is more confusing to use on-stage 
than 2. Second, many musicians leave reverb on all the time and the footswitch function is not as important to 
them anyway. Third, we would have to raise our retail price in order to produce a 3-switch footswitch.  The in-
crease in cost would be more than you would pay for a single footswitch at your dealer.  If you find that you must 
switch all 3 functions, here's how to do it: 

1. Plug the Tube Works footswitch into jack #1. 
2. Obtain a regular push-on, push-off footswitch with a 1/4” plug and plug into jack #2.   

You will now have Reverb/Channel on the Tube Works footswitch, and Stack on the single footswitch.  
NOTE: Channel will not function if you reverse the two footswitches.  
 
We have been asked, "Where are the tubes?"  
Answer: They are inside the chassis for protection and shielding as they generally will not require any attention 
for years outside access is not a necessity.  
 
WARNING NOTICE — Use of this device constitutes an agreement. See "Warranty" section for further details.   
 

 

 

•

This amplifier was designed primarily for musical instrument amplification.  It will add warmth and definition 
to your sound 

 

•

Use with speakers or cabinets capable of at least 100 watts RMS continuous power.  Remember that Mos-
Valve can easily produce 100 watts per channel under typical overdrive conditions. At least 100 watt speak-
ers or cabinets are highly recommended if you intend to use the amp at high power output. 

 
MANUFACTURER IS NOT RESPONSIBLE FOR ANY SPEAKER FAILURE WHILE USING THIS EQUIP-
MENT.  THIS INCLUDES THE OEM SPEAKE SUPPLIED WITH THE AMP.  SINCE TUBE WORKS IS NOT 
THE MANUFACTURER OF THIS SPEAKER, THE OEM MANUFACTURER’S WARRANT APPLIES.  BURNED 
VOICE COILS ARE NOT COVERED UNDER ANY WARRANTY.  
 

•

A certain amount of heat during operation is normal. The MosValve amplifier is biased in a manner that even 
when idling there is some heat present. It is best to keep the amplifier away from obstructions which might 
restrict normal air flow through the cabinet. Never block the vents on either the bottom or back of the chas-
sis.  

 

•

Never load the speaker outputs with less than 4 ohm loads. These can be a single speaker cabinet or a 
combination of two cabinets including the combo enclosure itself.  Combinations: One 4 ohm (or higher) or 
two 8 ohm (or higher) NOTE: Speaker supplied with your amp is 100 watts, 8 ohm.
