Tom:
"....aren't these the drip bowls that GE advertised as cleanable in the P*7 oven?"
That might be. The bowls were rough and dark, which could indicate cleaning in the oven. However, the 900F temp of pyrolitic self-cleaning is way up there for aluminum, which has a melting point just over 1200F. I'm not sure that would be good for the bowls.
Anyway, I personally won't be doing that. I like shiny burner bowls; they reflect heat better and they look much nicer. I like nicely Brillo-ed aluminum; it always looks so Suzy Homemaker, LOL.
I know someone with a brand-new GE self-cleaner (the "P*7" trademark is, sadly, nowhere to be seen on it), and that range has porcelain-coated one-piece burner bowls and porcelain-coated oven racks; a cleaning cycle doesn't affect their appearance. That's a change that makes sense. The trade-off is losing some of the chrome-y goodness of older units.
Latest news flash: The Sensi-Temp burner is working, so far as I can tell!
And P.S.: That photo of the range's transport made me giggle. I certainly didn't move here in such spacious comfort!
