I just purchased a NOS Rec for my Mazerati, but when I was changing out the old one, one of the contact pins came out with the old tube, so I just inserted it onto the NOS tube same position and plugged her back in. It works so I'm not gonna touch it, but is this going to be a problem??? Are the pins wired in some way or does this happen often???

As long as you put it back in the same hole - no problem. Since it works, you obviously did it right. The pin that came out didnt have a wire soldered to it. The pins are held in place by inserting the pin in the socket, and spreading little metal keeper wings to hold it in. The come out sometimes, but it's nothing to worry about.

There are 5 pins on most rectifiers but only 4 of them are hooked up so sometimes the 5th pin will pull the socket pin out. No big deal, just stick it back in like you did and continue rocking!

Leave it out , it isn't the cause of the recto blowing and it serves no function at all. Mine came out in my Maz 18 years ago and I tossed it in a parts bin. The socket pin that pulled out isn't wired to anything , why risk it falling in the chassis and rolling around and shorting something?

Why is it in there in the first place? Is it just part of some standard part that the Doc didn't want to mod or take out when in production? Yeah, I would hate for it to fall into the chassis and short out something major.... So looks like I may need a new rec tube, dang

Sockets come standard from manufacturers fully loaded with receptacle pins , because they can be used with a lot of different tubes: 6L6 , EL34 , various rectifiers- even octal based relays used in industrial machinery. The pins are held in place with small teeth that lock into the base material. When they aren't wired and a pin from a tube is inserted , they can pull out. Sometimes , but not always. I'm sure Doc & company don't want to waste time pulling the things out , as they don't hurt anything. Sockets in the old days had the receptacles molded in and didn't tend to pull out , new manufacture doesn't do it that way anymore. It's really no big deal , put it in an envelope and forget it. And it does sound like your rectifier is about to give out , sorry about that.

Only four pins are used to operate your amp. The fifth pin is used to flash the getter in the tube during manufacturing to completely vacuum the inside of the tube.
NOS tubes have fatter pins and can extract that unused pin from the socket. The pin will only come out the top side, will not come out the bottom and enter your chassis.
You'll find a small triangular barb in the center of the pin, push that barb a bit out with a small flat blade screw driver. Insert the pin back in it will snap back in and not come out again. Or you can put it in a envelope and not worry about it.
