Is matching inverter transformers really that necessary?

Guy had a broken inverter transformer, so scavenged a random transformer... and wow, it actually works?!

Perhaps the transformers aren't that critical!

He did not say what the resistance on the replacement transformer was compares to the originals. It probably was a close enough match to allow it to work properly.

Looks like he used a notebook transformer.
I wonder how long it'll last...

I tried inveter transformer sub (not the same P/N) in the DELL once, looks exacltly the same, but not the same impedance or the inductance. The Monitor worked for 2 weeks before it came back with blown MOSFET's.
