I installed Cardas binding posts on an old Eico HF-89 that I rehabbed a while back. You can view pictures of it at http://www.raleighaudio.com/tracy.htm if you are interested. You will need some metal working tools (holes for the Cardas posts will need to be drilled) and a soldering iron, or better yet a high wattage gun (Cardas posts have a lot of metal and take some heat to solder) and some soldering skills. I would also recommend using the older Cardas quad eutectic solder with lead. It flows better and will leave a better connection. If I remember correctly, you will need to remove the posts from the plastic base to solder leads to them. You don't what to melt the base! Good luck.
