In which I concede I am a total noob - the 2KBB60 actually has a completely different leg layout (-~+~) to the KBP206G (+??-), despite having matching dog ears. I think I'll be ordering a new KBP206G!

Thanks for your time

I hope I put them in the right way - the one I was least confident in was the PWM, because I got the same part number for that one, but they looked different - the original one had a notch centre left (that was also marked on the circuit board) and the new one had a spot bottom left, so as both markings were on the left and the text on the chip was the same way up, I figured that was the right way.

On the bridge rectifier:
On the one I took out (KBP206G), measuring 1>4 gives me a reading that when I checked it was about 1.7 and climbing infinitely in one direction, and nothing...

Sorry it's taken me so long to acknowledge the reply you were kind enough to send.

I pulled the mosfet from the board and tested it with my multimeter and it checked out as good. Eventually I plucked up the courage to order a whole bunch of components and trial-and-error it.

I replaced, in this order:
The mosfet
The PWM
The resistor that was showing the dark marks, just for the hell of it
Diode D6 (not sure how I decided on ordering one of those to replace, but I did)
The bridge rectifier

And testing after each replacement blew...

Thank you for the reply! Before I go to bed, I have just given it a quick test with the multimeter (without removing the mosfet from the board) - there is continuity between the drain and the source, with the red and black cables either way around. That probably means it's toast, right?

Hello Badcaps!

I am trying to troubleshoot my Allen & Heath Xone:02 DJ mixer. I have had this for somewhere close to 20 years and have played music through it in one form or another pretty much every single day since I've had it, though these days it's usually from a wireless streaming receptacle (Apple Airport) more than the turntables that are also connected to it.

This week my music stopped working, and after a bit of a wild goose chase, I realised my mixer was dead. I checked the 500mA fuse in the device beside the power supply and found it was blown, so I replaced...

Hello Badcaps! I am Ricky, and I like to make things. I'm not afraid of a soldering iron, but can get a little out of my depth with electronics. My grandpa was an electrical engineer, and he used to be who I went to for electronic advice, but it has now been a few years since he passed away, and instead I am turning to the wide head of knowledge that is the internet instead. Thank you for having me here.
