Trafos in Germany

[A.S.P.]

Hello German Subscribers,


I will be in Germany next week.  I am trying to decide on a small rack of 
gear to take with me.  

How hard is it to get external transformers for the following gear:

Alesis MMT8

Yamaha RY30

Lexicon Vortex, Reflex, etc...

Kawai XD5

Boss Pedals

?

How about internal trafos for gear like Korg SQ10 or Roland CR78?

I will be in Kassel and Koeln.  Does that affect availability at all?

Also. how hard would it be to rent a Doepfer MAQ in Koeln?

R?
