Doepfer

Wondering if Dieter or anyone can help with this one:

I've had 3 G6 racks for a couple of months. None of them have been problematic until 
yesterday, when one of them blew a fuse. I replaced the fuse, and everything worked 
again, until today, when the fuse blew again. I removed most of the modules, and the fuse 
blew. I removed all of the modules, and a fuse blew. I then tested one of the other cases 
by turning it on a few times, and eventually one of those blew too. I have tried different 
surge protectors, different cables, different electrical circuits in my apartment -- same 
thing.

It would seem that this would indicate either 1) some major problem with my building's 
electricity (possibly but unlikely), or 2) two G6 power supplies that went defective at 
exactly the same time (possibly but unlikely).

Any thoughts? If it is some crazy problem with New York city's electrical grid, I would 
imagine the Doepfer racks wouldn't be the only things susceptible. But the fact that two 
different boxes, tested with all different numbers of modules (none, a few, a bunch, and a 
lot) kept blowing seems downright weird.

I am using 1/2 amp slow-blow fuses, and tested the outlets in the apartment, which are 
all running pretty close to 115v (~117, ~120, etc.).

Is there something completely stupid and obvious that I'm missing?

Thanks anyone for any help.
