>> When inspecting further I noticed that the one of the two cooling

>> The glue of the capacitors was loose so it felt all very wobbly.
>> Than I opened another MC100 and noticed a different board inside

>> Are there different versions?
>> On the broken PCB was written: version 1 2016.
>> A bit confusing.
>> I ordered a new one this evening from Thomann and made an ticket
>> for returning the faulty one.
>> Glad it didn't break my new module.
