Hola, mi parlante tenía roto una resistencia de 0.1 ohms, la remplaze y suena genial, solo tiene un inconveniente, y es que cada vez que lo enciendo emite un ruido, la primera vez al encenderlo después de un tiempo no hace ningún sonido, pero las veces siguientes lo hace, ya revise capacitores y todo está bien, no ce si sea problema de voltajes de algún regulador o los mismos transistores, pero cuando curse mecatronica en la escuela no aprendí mucho, fue más teoría que practica, y pues como ya no continué la universidad pues me quedé solo con algún conocimiento teórico, por último la llevé con un técnico en reparación y tampoco pudo hacer nada
I dont know that because fishman doent release schematics. But they will answer your question if you email them. They are at least helpful unlike many companies.
Channel 2 is significantly louder on my amp. Yes there is more static when I crank the gain for channel 2 but it's also way louder. Idk. I messaged fishman for info.

I have a loudbox performer 700bt with the same problem in channel 1 but i don't see a Q10 in it .
Can you tell which component I need . Thanks , Mitch
Thank you.. I have the same issue... Would you say that the Q10 (MMBF4392) is the same for channel 1 and 2 ?
can I bypass the head part and use the speakers as a speaker cement for a different amp head..? Any idea how to build a speaker unit by itself
Hello. My loudbox mini's reverb is not working for mic channel. Do you have any Idea how to fix it?
Hello again , I just retested it and found that channel 2 also has white noise but not as much
fishman doent release schematics. But they will answer your question if you email them
My Loudbox Artist has EXACTLY that same problem, same channel. Where did you source the part?
probably mouser
My channel 2 is much louder than channel 1. Is that the same with yours? Do you have a slight white noise when you just turn on the master volume?
Thanks for this. Do you happen to know if the the part number is the same for Channel 1?

Same issue but in Channel 1 (Top) which FET needs to be replaced for the top channel
I found the FET Q10 on the top board channel 1, will replacing that FET on the top board eliminate the white noise on channel 1?
Channel 2 is significantly louder on my amp. Yes there is more static when I crank the gain for channel 2 but it's also way louder. Idk. I messaged fishman for info.
What if the speaker is making no sound?
If it powers up but makes no sound could be blown speakers. test them with a meter, is a good starting point.
Well this video could go into a little more detail that would help
I would keep that removed FET for making a pink-noise generator
same issue on mini
schem. i find has different part designators.. eg 5532 is u3 and tl074 is u4 but a 33079 is used in schemo instead of ne5532 as u9 and 074 is u10
ps and shows 1/4" in instead of xlr
nvr mind- found it- no fet pre on this one- 5532 likely issue
I have fishman mini too, same problem with you, do you fix it???
