I purchased my MingDa amp already extensively modded from James (Crazikid) a couple months ago. Myself and others have been very impressed with its performance, particularly when partnered with the kdac and ML1's.
Due to the number and size of Jensen caps added to the amp, it created problems with mounting them securely and safely causing them to be placed into a cardboard box with long flying leads as a temporary arrangement until a method was devised where they could secured and attached to the amp.
MCB and I had thoughts about different ways of mounting the caps without disturbing the integrity of the amp and of course something relatively easy. That's when we came up with the dropbox.
I guess the pic's speak for themselves.
