I will certainly agree the MAM 505 is a mutha to get up to temperature. From a cold start, it takes 4 hours. Even then, the dome is not all white. It takes quite a while to master or at least, get the hang of it. It came out of a college town restaurant that made pizza. They had a deck oven in the kitchen and burned wood in the damn thing just for the effect. A college kid doesn't stand a chance. Once home, it took forever to burn it out.
It's nice you found a solution for your oven management.
