Gryphon Apex Stereo power amplifier
Some time ago, an amplifier in for review caught fire when first powered up. I don't mean it smoked and sizzled and shut downI mean that actual flames shot through the top grate. Fortunately, I was able to grab a kitchen fire extinguisher and douse the thing with foam. (Sorry, this was decades ago, and I don't remember the brand, but I think the company had a fire sale and was shut down.)
