hi everyone, recently i have a problem with my amplifier, it's a Fender 400 pro bass, head amplifier, the problem become one day in the studio with a voltage problem, so, my amp is not making any sound, the lights are on, the power it's ok, but no sound , i opened and i see some resistors totally burned , so the problem is, i don't know what is the value of the resistors, i tried to search in the web the schematics but i can't find it ,

i hope somebody can help me to find the value of the resistors, or the schematic, i enclose some pics of the damage and the board.

(i remove the burned resistors of the board)

the three resistor are connected to the line out jack, so I think that might regulate the impedance of the line out, and all three are of the same value, a low value like 10 ohm or something like that, but i want to be sure.

I hope you can help me with this, I would appreciate it very much, thank you very much

(sorry for my really bad english, i'm from chile, a south america country)

Hi nattino,

You might have to contact Fender to get a PDF or hard copy of the schematics.
