So the tech replaced two output transformers before he informed you about the impedance mismatch? That sucks!

IMO Neil's advice (while appreciated) is sort of only partially correct and to be honest I wouldn't recommend following that advice.

A couple huge flaws in that logic..

He doesn't seem to address the difference between doing this with a solid state or tube amp

He seems to suggest that this is a generally reliable solution, but it completely depends on the amp. There is definitely potential to damage your amp by following that advice

Many amps can handle an impedance mismatch without any issues. For example many Fender combos have an extension speaker jack which puts the extension cab in parallel with the internal speaker. In the case of a 5e3 for example, the internal speaker is 8 ohm and when connected to the recommended 8 ohm extension cab, the total impedance is 4 ohms. Note that in this case you are using a smaller speaker load than recommended which, contrary to Neil's advice, does not damage the amp. So what I'm saying here is basically just connect the correct load or do your homework to figure out what you can get away with, but do not just blindly follow advice about mismatching the speaker load if you care about your amp
