Okay....just used the Farberware electric percolator this morning for the first time. Remember, this is an old one so I was a bit nervous. I added the water and coffee grounds and plugged it in. It brewed nicely but I didn't know when it was finished. It did begin to make a different sound so assumed it was done. I unplugged it and poured a cup. It was pretty good but I could have made it stronger.
This little gem didn't come with instructions.
Thanks everyone for all your responses. It's nice to know so many people still use percolators. (like the old days)
