How to remove shredded venturi tube? (on thermador gas range)

When this stove was serviced a few years ago, the tech had to drill out one or two venturi tubes.

I just had to drill out 2 of 4 in order to remove the top of the stove. They were completely siezed up.

So… the top of the stove is off… but how do I get the remains of these venturi tubes out of the threaded base?

You don’t. Unfortunately, you’ll now need to remove the nut holding the jet holder up into the burner bracket and replace said jet holder.
