You remind me of one of my favourite quotes. Some HiFi magazine was
reviewing an amplifier with staggering (at the time) output power of
several hundred watts per channel which claimed to have complete output
protection, even against shorting. So they decided to test it by taking
the leads out of the speaker while running at full volume and brushing
them together.
"The result was large frightening sparks" has stuck in my memory ever since.
I'm glad your amp is back in business.

Well, those several hundred watts WOULD make some nice sparks. But
was any harm done?

I tell you what though, the resisters load I was using got f**king

I remember Crown (or Amcron as they were known in the UK at that time)
demonstrating the robustness of one of their large amps at a hifi show by
connecting the speaker outputs to two parallel bars and putting a
screwdriver across the bars. This gave a shower of sparks whenever the
screwdriver was moved.

You possess a scope but ask about getting a power amp repaired?
