Stan Curtis 60W Class A Amplifier from ETI
Stan Curtis was involved in both engineering and management roles in companies like Quad, Cambridge, Rotel (a family owned Japanese brand) Mission and Lecson to name a few. He is primarily an audio business consultant and remains highly respected and a noted product designer within the sector in his own right.
This is his 60 Watt DIY class A amplifier published in ETI in 1985 which has been referenced on numerous web sites and publications over the last 25 or so years. It’s a rather complex design, but, 60W of class A power translates to a BIG amplifier with significant standing dissipation.
