OK, I was finally able to dig through my photos and found some that will give you a pretty good idea of the setup. I'll post them in a series here.
First, here are some photos of version 1.0 of the electric grill. It worked on 110v / 15A. I think I used a heating element in the 1200W range to make sure I kept a cushion on the maximum rating. It worked and was great for smoking. It could get in the 200-250 degree range in about 30-60 minutes if I remember correctly.
These photos show:
1) The first firing of what I believe to be the first ever electric KK. Dennis may know better.
2) Proof of the first time it hit 400 degrees. It took a long time to get there. Maybe 4 hours or more? A 110v / 1200W heating element just doesn't have enough power to heat up all of that thermal mass.
3) The electric KK in action, cooking a Wagyu Culotte Cap with a smoking box
4) The finished steak. It was delicious. You can see that it cooked very evenly and had almost no grey ring. It was like cooking sous vide. I believe I needed to get the sear in a pan or the broiler.
