Can any stereo amp be bridged to mono ?

I came across some professional audio pdf's when researching a Yamaha P2200 amp. They state this is easily done ( with their amp ) with a splitter transformer on the input with one side out of phase with the other going into each channel; then connecting the speaker to the 2 positives. Would this work with any amp ?
The pdf is at this address - check section 6 page 17

Yes, but only if the amp uses a common ground.

Also remember that a bridged amp sees 1/2 of the original speaker resistance. If your speakers are 8 ohm the bridged amplifiers only see a 4 ohm load. Make sure your amps are stable at the reduced load.
