Carver’s company, back in the late Seventies/early Eighties, attained variations of, ’PHLAME or FLAME Linear’, as it’s moniker, among the electronics repair community. That was the result of the frequency, with which they(400s and 700s) showed up on our benches, with their outputs totally/dramatically fried. We usually got whatever was connected to the outputs, in for repair, also. Obviously; what units got to the shop hadn’t burned anything down, or they would have been consumed as well. I never heard of his later designs exhibiting like tendencies. If some of those early models didn’t burn something down, as a result of flammables in close proximity, I’d be surprised. Any records of such fires(IF ANY) would be hard to recover, having occurred way before the ’Net existed. (Just my observations)
