Troubleshooting.Tips.
#
No#output.#The#power#switch#is#on,#but#the#power#LED#is#off#and#tubes#do#not#light#up.#
•#AC#cable#makes#a#bad#connection#in#the#IEC#connector.#Please#check.#
•#Mains#fuse#is#broken.#Please#check.#
•#PTP™#(Power#Transformer#Protection)#protection#may#have#switched#off#the#power#transformer.#
If#so,#the#amplifier#will#switch#on#again#after#the#internal#temperature#of#the#power#transformer#
returns#to#normal.#Overheating#might#be#caused#by#higher#environment#temperature#than#normal#
or#heavy#use.#
#
No#output.#The#power#switch#is#on,#the#front#LED#is#green#and#tubes#do#light#up.#
•#Adaptive#Auto#Bias#Board#fuse#is#broken.#Please#check.#
#
No#output.#The#power#switch#is#on,#the#front#LED#is#red#and#LED#in#front#of#a#power#tube#MIGHT#light#up.#
•#BTITM#circuit#has#switched#off#the#high#voltage#supply#to#the#power#output#tubes.##
This#can#happen#for#example,#when#one#(or#more)#output#tube(s)#draw(s)#significantly#more#
current#than#normal,#like#what#can#happen#when#a#loudspeaker#terminal#is#shortGcircuited#with#the#
volume#turned#up.##
•#In#case#of#an#internal#output#tube#failure,#the#BTI™#circuit#understands#that#there#is#a#new#
situation#which#can#cause#harm#to#the#amplifier#or#the#loudspeaker,#and#the#high#voltage#power#
supply#to#the#output#tubes#is#interrupted#as#a#protective#measure.#The#front#LED#will#turn#red#and#
you#might#see#a#red#LED#in#front#of#one#or#more#power#tubes.#To#reset,#switch#the#amplifier’s#
power#off#for#at#least#two#minutes,#then#switch#back#on.#Of#course,#this#should#only#be#done#after#
the#cause#of#the#failure#has#been#identified#and#resolved.#Switching#the#power#back#on#too#early#
can#fool#the#BTITM#circuit#into#acting#as#though#the#problem#has#not#been#totally#resolved#and#it#
may#put#the#amp#back#into#protection#mode#again.#So#be#sure#to#give#it#enough#time#to#reset.#
#
Noise#or#hum#coming#from#one#channel#(eventually#when#you#change#your#volume#setting).#
•#Noisy#tube.#At#first#swap#the#two#inner#small#tubes#left#to#right.#If#noise#follows#the#tube#swap#then#
you#have#found#the#problem#tube.#If#noise#does#not#follow,#swap#the#next#set#of#two#small#tubes#
left#to#right,#eventually#the#next#set#in#case#your#amplifier#has#6#small#tubes.#
•#Possible#bad#output#tube.#Swap#the#output#tubes#in#pairs#from#right#to#left.#If#hum#follows#the#
swap,#swap#the#far#left#and#far#right#tubes.#If#the#hum#returns#to#the#original#problem#channel,#you#
have#found#the#problem#tube.#If#not,#swap#the#inside#output#tubes#left#to#right.#
