Again, here is another popular design with higher power output. Do note the protection circuits that have been incorporated; they worked very well indeed, as many would gladly attest. Quite a few of us had found that with an unregulated power supply and good components and a large, heavy heatsink, this design could take some beating! The circuit works very well without the protection circuit too, and for the experienced and careful constructor, the design has many merits even toay, I guess. If one doesn't want to 'brag' about the 'watts', this power amp could provide you with a solid foundation for your home-built system. Naturally quality of build and "setting up" the power amp are key factors in its sonic quality and reliability. For the younger brigade accustomed to "plug and play" with IC-based designs, setting up a quirky, high power amp would be something like a tight-rope walk, the art of which, once mastered, becomes easy and even enjoyable!
I am sure this foray into the past shall serve as the trigger for many new explorations, especially of a mature kind in search of true fidelity.
Happy DIY-ing !!
