well, I've got some pictures to show you. First off it should be known that I was only attempting to change the rectifier in my Maz 38 NR. I kept blowing fuses and I figured that this was the problem. Upon gently pulling the rectifier out of it's socket (that includes loosening the screws on the hold down mechanism and pulling out using gentle "swirling" motions. (sorry, couldn't find a better way to word that)) a little piece of the amp decided to come with it...much to my dismay I might add. Of course I have a show tomorrow and will have to use an AC-30...aka, my playing will be sub par(even more so than usual . Check out the pictures and let me know what you think. I'm thinking that this may have to be a Z fix seeing that the rectifiers location is under the top layer of board. Any questions feel free to ask. I really do appreciate the help here on this forum.

That is just an unused terminal of the tube socket. not at all unusual for this to happen.
Leave in on the old Rec since it's not needed and install your new rectifier.

WOW! Thanks to both of you for your speedy and definitive responses!
You know, this does make me wonder of course...why have it if it isn't used...apparently other amp designs do use this?
Lastly one more question...I have a certain solder joint that keeps coming undone. I was wondering if you could help reason as to why this might happen. I'll post a pic soon.

The first photo is the solder joint in question. That fuse never gets knocked around or anything like that, so I'm a little curios as to why it keeps breaking solder. I have had it resoldered about 6 times including once or twice by the Z staff (the only reason I say this is to let everyone know that it's not just Joe Blow sloppin' solder everywhere) As you can see from the second picture, I had to pull the wire out of the board in order to reach the fuse. This last solder job has lasted for about 4-5 months now, and will hopefully continue on alot longer. (knock on wood) Last but not least, is it true that if the rectifier goes bad it typically means that it is time to replace your power tubes? sorry for all of the questions, but I really appreciate it!

Rectifiers can go at anytime, especially new production ones. If the amp fires up with no problems after replacing the blown one, you are good to go.
