if it ain't Baroque ...
I am thinking of gutting a Rogers Ravensbrook amplifier and replacing the board with a class D amplifier or two. The case and fascia of the Rogers fit in with the kitchen decor, but the sound is behind a class D amplifier I'm using (with JPW Sonata 'speakers). The problem is that the (several) low power class D amplifiers I have used seem to run out of steam quite quickly. Looking at the data sheets for the amplifier chips, I notice output is usually quoted at 10% distortion, yes 10% distortion! The Sonatas are rated at 60 watts (not that I play loudly while cooking!) but getting a class D amplifier to produce a genuine 50 watts (at <0.1% distortion) is going to need an advertised output around 300 watts!
Has anyone gutted an amplifier and replaced the board/s with class D amplifiers?
