Esoteric P/05 and D/05 - where are fuse's ?????

......I have upgraded the fuse's in my other pieces and for the money, they do make a nice improvement. I also think that they are better built than what I have replaced from the original maufacturer's - so that is also comforting to know that if anything were to happen, there is some added insurance. So, do these pieces even have fuse's and if so, please let me know the amp and whether they are slow or fast burn.
For general replacement without specifications. I suggest to use 5A Slow for optimal performance.
