Has anyone had experience using microwave oven door glass as a shielded

I'm considering a three-tube 3500ZG amp as one of my winter projects,
and was thinking it would be fun to show the tubes with their cheery
cherry glow.
How may output Watts will you be producing?
(or are you just going to detune the plate until everything turns red)
My mw ovens have a steel plate with a bunch of holes in it behind the
glass to block the RF, this shouldn't be much of a concern at 29 MHz and
below.
