The Behringer B2301 Repair
In the last episode of the B2301 saga, we watched in horror as capacitors exploded in our beloved monitors. Now begins the task of cleaning up the destruction.
As a quick recap, I had a Behringer B2301 studio monitor fry on me. It turned out to just be some snubber capacitors across some rectifier diodes exploding, so there was no significant damage to the unit. Chances are the unit would function just fine without them, but I’m replacing them anyway since there is no other filtering on the voltage rails which supply the amplifier ICs.
That being said, I picked up 8 beefier, non-explosion rated capacitors from Digikey. I also bought 8 new fast-recovery rectifier diodes. Because the new capacitors were so much larger than the old ones, I piggy-backed them on top of the diodes rather than try to fit them in the old PCB holes. This was also necessary because some of the tiny copper traces to the capacitors had been vaporized when the old capacitors failed.
The old diodes and capacitors came out and the new diodes with their piggy-backed capacitors went in. I also took a few minutes to replace the stiffening capacitors. If you decide to replace these, realize that they are shorter than standard. I didn’t and ended up having to install some 1/8″ spacers between the amplifier chassis and speaker enclosure to get everything to fit.
That is the end of this story. The monitors have been working fine since the repairs. This was a pretty simple repair; diagnosis was easy and treatment consisted of just replacing parts.
As always, make sure it is unplugged before you take it apart.
Update: The parts list as requested:
+ DigiKey indicates that they no longer will be stocking these Panasonic capacitors. As the time of writing, they still have plenty in stock but once they’re gone, DigiKey No. 445-2429-ND made by TDK should be a functionally equivalent. Any 0.01uF ceramic rated 200V or better should do fine, though.
++ These capacitors were slightly too tall as previously mentioned. A better replacement might be DigiKey No. 338-1649-ND made by Cornell Dubilier. They are shorter and should fit comfortably but are rated 3000HR@85ºC and have a higher ESR (68.0 mΩ versus 49.0 mΩ for the Panasonic) but should work fine in this application. They also happen to be half the price of the slightly too large Panasonic caps.
