What are the replacement part numbers for the boston acoustics mcs130 subwoofer transistors Q10, Q10b, abd Q11?

Trying hard to replace the fets of a Boston Acoustics MCS130 subwoofer # Q10, Q10b, and Q11, but I can't read the part numbers off of the transistors themselves. They are fets. Any help is much appreciated! Thank you!

Is the sub dead? Because this is usually caused by ZD3 being shorted....not the transistors.

    hi steve i have the problem were ZD3 has blown but i cant tell what it was what part do i need thanks

  • Steve K Mar 17, 2014

    ZD3 is a 18v zener diode. also check R9 on the back of the board, if ZD3 shorts, R9 may become open - it is supposed to be 10 ohms.

    Do you have a Schematic/Part list?

    I also have an MCS130 with the same problem. Will turn on but no sound. Originally problem was a 60Hz humming sound, replaced the main capacitors C04, C05, C06, C07 and the humming is gone, but no sound. To be honest not sure if there was sound while humming was on since I didn’t try is because humming was quite loud. Based on the answer above I should look for ZD03 and/or R9, but can’t find them. Any pointers on where exactly are they ?. @Steve. Do you have the schematics ??. Do you repair these units ?

SOURCE: how do i connect my boston acoustics pv800

You need to use the LINE LEVEL connection on the pv800 (usually a rca type connector cable) and run this cable into the back of the HK 520 Subwoofer PRE-OUT connector, be sure the HK Receiver menu speaker set-up option is set to SUBWOOFER "YES"

SOURCE: I have a Boston MCS130

mine had the same problem until it completely quit. unplug the sub and turn it over, press gently on the speaker cone, does it move freely, or do you hear a sort of scrapping noise? if it moves freely with no noise, its a dif problem than mine. if you do hear the scrapping noise, then theres a short in the voice coil, from what ive read you have to replace the driver (actual speaker part), its basically blown

My boston hps12 ho subwoofer blows fuse. what could be wrong


Fuses blow when there is an overload. The most likely cause is a short-circuited semi-conductor IE: a transistor or IC etc. If you find one of these devices inside it with a heat sink on it, that will be the most likely cause. Transistors can be tested with an Ohm Meter and in a short circuit fault such as this, it will be like you have put the two test probes together!

Zd 3 diode value on boston acoustic soundware xs 5.1 subwoofer


Hello
Did you find the value of ZD3.
I need it too.
I have the same problem, and I take out the ZD3 and the subwoofer works. But I'm not sure that is correct. I think it may be the circuit stand by.
