Miller & Kreisel KX10BK Subwoofer

[diymax62]

Hello to all,

recentrly I bought a defective Miller & Kreisel KX10BK Subwoofer, sincerely I hoped it was simplier to repair. I see a couple of transistor burned, but it seems thay aren't in the amplification path, more in the signal-sensing circuit to automate power on.

Anyway, I think it's quite easy to repair with a service manual, but I can't manage to find anything on internet. Can someone help me?

thank you

Hello OldDIY, thank you for the link, but the model I bought is quite old, it's not the X10 but the KX10BK, I asked some info about the circuit because of its age.

Anyway, taking a closer look it seems I confused a glued area with a burned one. I found a defective capacitor in the power supply and I will begin my repair attempts by replacing this component.

Anyway, any help with the schematics will be very appreciated...

Any updates on this? Were you able to get it running again just by recapping it?

Hallo cchean, no the problem was more diffuse, there are some defective transistors, I'm waiting for the replacement and I'll write a complete review when I'll manage to make it work again (I hope...)
