here's the email i sent to waldorf.


Hi. I own a waldorf micro-q and recently the wrong adapter was plugged into it by accident and the right adapter no longer works.

I have no idea if this thing is now toast or if it is fixable, but I noticed upon opening the synth that there are two seperate circuit boards. The board the power cable and audio/midi ins and outs are on and a seperate board for everything else. They were only connected via a gray pci computer cable. I was wondering if it was possible to replace just the smaller board with the audio/midi jacks thru u guys and if that would even fix the problem. I didnt see anything that looked damaged on either board and didnt smell anything burning, but I also didn't find a fuse either. any suggestions are appreciated.

They havent replied because I assume I mentioned that I had opened the case up. My warranty expired anyways hehe.

Ask on the Waldorf forum-I think I saw a question along the same line there a couple months ago.

As far as repair goes,get in touch with your local Waldorf distributor.If you had a serious voltage and/or amperage mismatch,you could have very well fried the DSP board
ew

what did you plug in (volts, amps, ac or dc?) and what is the real mQ one supposed to be?

if you put in too little voltage it shouldn't have bothered anything. Usually stuff just 'doesn't work right' in that case. If you put in too little current (amps) it would have fried the supply

if you put in too much current it just wouldn't have pulled as much and wouldn't be a problem except voltage wouldn't have been as it supposed to be (wall warts are not regulated - means pulling less current increases the voltage, but usually not that much)

if you put in too much voltage it could cause a problem. May have blown a fuse inside (never been inside a mQ so I don't know what's in there to stop this from destroying stuff).

If you reversed polarity, could be problems. Most power adapters are standard on their pos/neg sides though so probably not the problem hopefully.

actual waldorf supply:

input: 120v AC 60hz 19w
output: 12v DC 1000ma
polarity is positive

------------------------------------------------------
offending power supply:
input: 120VAC 60hz 50w
output: 9VAC 3500ma

Oof that was the last option. Yes putting an AC into a DC is not good either sorry

Still may be a fuse in there or a blown regulator because of the inverse voltage. Sorry no good news.

This makes me want to cry.

yeah its a cardinal rule of mine, like always backup your data

mark all wallwarts clearly the moment they arrive.
