A.C. MAINS

 IEC cable inlet – plug a suitable IEC power cable into this inlet to power your amplifier 

 

MAINS FUSE 

2A slow-blow fuse – used to protect your amplifier from voltage spikes or excessive current draw.  Replace only 

when necessary.  
 

HT FUSE 

0.5A slow-blow fuse – used to protect your amplifier, particularly during the event of tube failure.  Replace only when 

necessary.  
 

SPEAKERS EXTENSION AND MAIN

 

¼

” speaker cable jacks.  Use a 

¼

” speaker cable to connect your speaker cabinet to the 

amplifier using these jacks.  If you use one speaker cabinet, use the jack labeled MAIN.  If you want to run two cabinets in 
parallel, connect the second cabinet to the amplifier using the jack labeled EXTENSION. 
 

NOTE

 – never turn your amplifier off STANDBY mode without connecting the amplifier to a speaker cabinet or suitable dummy 

load!  Failing to do so may damage your amplifier! 
 

IMPEDANCE

 three-way rotary selector.  Set this selector to the position that matches the impedance of your speaker cabinet.   

 

NOTE

 – if you are using two speaker cabinets in parallel (ex – two 16 Ohm cabinets), set the impedance selector to half that of 

a single cabinet (in this case, 8 Ohms). 

 
EFFECTS LOOP RETURN

 

¼

” instrument jack can be used to directly interface the power amp of the SOY, thereby bypassing 

the preamp and using the amplifier as a power amplifier.  Conversely, this is usually used as the RETURN of the effects loop.  
Plug the output of your effects unit, or interface device (ex – C-lator, Klein-ulator) into this jack using 

¼

” instrument cable.  The 

effects loop in the SOY amplifier is passive. 

 

EFFECTS LOOP SEND

 

¼

” instrument jack can be used to directly interface the preamp of the SOY, thereby bypassing the 

power amplifier and using the SOY as a preamp.  Conversely, this is usually used as the SEND of the effects loop.  Plug the 
input of your effects unit, or interface device (ex – C-lator, Klein-ulator) into this jack using 

¼

” instrument cable.  The effects 

loop in the SOY amplifier is passive.
