Hifonics BX1000D

[streetilegalbass]

Hello, I am repairing this Hifonics bx1000D it came with problems in the output. Does anyone know if the 10uf 250v capacitors that go on C19C C20C are polarized or not?

Is there any marking for polarity?

 

[streetilegalbass]

the board is working but I'm not sure if it's polarized

 

[Perry Babin]

polarized capacitors typically have a line that indicates the negative terminal. Does this capacitor have such a marking?

 

[streetilegalbass]

yes, but they have already been replaced, I have a doubt that the led power is double led double?

 

[Perry Babin]

One LED has 3 terminals. The other has 2.

Does one terminal of each capacitor read 0 ohms to ground?

is that the problem I have is that the red LED turns on, not the protection LED the other one and the relay is not activated there is no audio the mosfet output is fine as well as those of psu leeo 46v 15+ 15- check the 2ohm resistances and pk diodes are ok does the same with or without the hip4080ipz

Can we deal with one problem at a time? Or have you solved the problem of the capacitors?

search the forum and find this photo you can see that they are non-polarized
