Fender Champ Amp Restoration

Soldering

• solder braid for removing old solder
• Weller 80 W soldering iron
• caig flux wash?

Resistors

• bias resistor?
• which are these in the schematic?
• from video bias resistor is a 470
• in the schematic a 470 ohm 1 w resistor comes off of the 6v6 in parallel with a 25uf 25v cap
