In the late 70’s a co-worker and myself walked into the Conrad Hilton Chicago for a Hi-Fi/Electronics show. I walked out with a used Phase Linear amp. My co-worker said “Don’t waste your money on that crap.” He was speaking in general about hi-fi stuff. He was married, I was single. Sure enough, the Phase Linear (some called Flame Linear) smoked and took out my speakers. Fortunately, as a DIYer I restored the speakers, but didn’t salvage the amp.
I often think about his criticism of those early days of my audio journey as I have gotten so much enjoyment from it all these decades. Short term, he was spot on!
