Yes- the 70's Phase linear did have a reputation for catching fire, as well as, those early editons of Counterpoint gear. After Counterpoint folded as a company, Mike Elliott did continue to offer repair/upgrades to his products.He is now retired. There is another Audiophile that took over that operation although it has been a few years back. A Google search might find the latest repair/upgrade tech currently.
Happy Listening!
