There!are!two!amplifier!PCBs!included!in!the!kit,!one!for!each!channel.!Start!with!
one!of!them.!
!
On! Side! B! of! the! amplifier! PCB! (note! the!B! side! marker),! place! and! solder!the!
valve/tube!socket.!Ensure!that!it!is!sitting!correctly!and!leveled!with!the!PCB.!It!
is! important! to! sit! the! socket! correctly! (the! axis! of! the! socket! and! PCB! are!
parallel)!as!this!will!determine!the!angle!of!the!valve!when!it!is!inserted.!!
!
Place!and! solder! all! the! resistors.! Follow! the! labeling!on! the! board! against! the!
labels! of! the! resistors’! packaging.! It! is! highly! recommended! that! you! double!
check!the!resistor!value!using!a! digital! multimeter!against!the!labeling!as! well,!
