David's Hatton's reply gave me a thought. Maybe my frame is too close to the tube's?
Maybe the corrugations were because of the proximity of the tubes? They certainly ran in the same direction.

I built my pizza oven myself following the directions in The New Platinum Print book (Carl Reese & ???). A friend wired it for me.

Loris how do I increase humidity?

FWIW, I tried this idea. For me it really didn't help and caused waffling of
the paper, but I had a pretty tight frame to begin with. The best solution
is to use a vacuum frame though I doubt Jon has the time to implement that

Another alternative is to use some of that very thing yellow soft foam sheet
material that is used for packing. It is around 1/16th inch thick. It
compresses where you don't need it and adds some pressure where you do. Put
it between the back of your coated paper and the "door" of the frame.

Another problem persists though .
To help improve flatness of the paper and negative sandwich I use a piece of
4 ply black mat board in my contact printing frames. It is cut the same
dimensions as the inside of the frame. More than likely this will help
flatten things nicely.
