Doepfer MC100 small case raw psu problem

2016-11-28 by jaccoville@yahoo.com

Hello there,

Last week I received my third MC100 raw. 
After putting in a module and plugged in the adapter the module behaved strange. 
After measuring the voltages I noticed that the +12V pin was about +6V, the -12V side was good. 
When inspecting further I noticed that the one of the two cooling radiators was hot , the other slightly warm. 
The glue of the capacitors was loose so it felt all very wobbly. 
Than I opened another MC100 and noticed a different board inside with 4 capacitors glued together and an other pcb layout. 
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. 

Best regards,

Jacco Ville
