but why only 100 watts? don't you need 1/2 the wattage input for 100% mod?

The mot core is for 60 Hz. No filament winding on a MOT is going to carry any wattage greater than needed to light the tube:

However if you wish to smoke it and a high power music amp, feel free. Post pics, though.

to repeat

The mot core is for 60 Hz.

Recently there was another thread dealing with using non
audio iron core transformers for audio.
