I have the capacitor replacement kit for my Beogram 8000 and am going to attempt using it this weekend. I've not done anything like this so it might end up a catastrophe.
Anyway I was reviewing the diagrams to make sure I knew what I was going to do and on the back side it says "When replacing C27 introduce connection as shown and make sure to connect to C27 (negative pin)."
I'm not really sure what this means and it appears as though the existing capacitor has 4 pins to the new one's 2. Am I supposed to solder a wire between the two unused holes? Or from one of the holes to the negative pin on the new capacitor?
Thanks in advance
The Beogram 800x series can be a tougher job than it appears. There is a lot crammed in to those small boards.
Here is a picture of a Beogram 8002 restoration where I used one of Martin's capacitor kits. The big 2200uF capacitor had a mounting base the attached to the negative lead. I used some needle-nose pliers to pop off that base and re-used it on the new capacitor. That way I didn't have to run any wiring on the trace side to account for the ring being gone. If you don't re-use the ring, you need to account for the ring routing the node, that the negative lead goes to, to the various places on the board.
Of the four pins on the original capacitor for position C27, the center pin is the positive lead.The three remaining pins sitting in the circumference are all negative. Two of the negativepins solder pads have copper traces connected to them so when you take out the old capacitorthe interconnect between these pins (that was previously made through the metal body ofthe capacitor) is lost.You will have to reestablish the missing connection by introducing a pieceof wire connecting the two used negative pins (the third pin in not used so doesn't need toconnect to anything).
The new capacitor then connects its positive pin to the center pad and its negative pin to the interconnect, you introduced.
