Hi everyone, I have a pair of b115 that do not light, I checked 5V regulator and optocoupler and they are OK, the fuses too, the MOSFET ok, can you help me please, there are no network diagrams, thanks

I would check the diagrams of the same series as B215, B215D, etc., just change the hardware such as USB, wireless microphones and maybe limiter-compressor or cross over, I'm almost sure use the same output and source stages.

... unless they are of smaller diameter of horns for example of 12 "and 8" then they change the stages,

Thank you, I have already reviewed them and have nothing to do with each other

is not oscillating, this is due to a small capacitor near the transformer. that mark misses a lot and lacks that CURE THIS PHOTO, TAKE FILTERS AND MIDELS OR CHANGE https://www.facebook.com/photo.php?fbid=1808449809400862&set=picfp.100007075815580.1808449806067529&type = 3 & theater

THESE ARE THE MAIN FILTERS THAT MAKE THIS BIT NOT HOLD. GREETINGS TO ALL AND I HOPE THEM SERVE THE TIP! AND AS THE COLLEAGEMENT OF THE QUESTION THAT HAS BEEN SUCCESSFUL BUT DO NOT HESITATE IT MAY ALSO BE FILTERED EVEN THOUGH THEY ARE NOT FATTY OR FELLOWED IT IS NOT NECESSARY THAT THEY ARE PHYSICALLY MALOBRATED TO FAIL.

I still do not finish, I think I will end up changing all the small filters, so far all I have measured give approximately half of the value, the esr are above 18ohm and the vlost walk above 28%, not counting 3 that were exploited underneath and with the glue did not see, I had never touched a team with so many bad filters, I never really thought the problem was out there, as soon as I changed everything I told you what happened, again thank you very much

Very well I hope this theme stays for future people who consult something similar. greetings and here we are for the next one.

As it is not going to be colleague you find your capacitors and bad resistors if you are reporting that the voltage to which it is subject undergoes very high variations lol

Colleague xXBlueDemoX at no time did I mention tensions or resistors; the ESR is the internal resistance of the filters and the vLost is the loss of value in the filter.
