Hi All, Just finished my DIY sub + amp, and am not happy at the moment with the amount of gain it supplies to the signal. The amp itself has a gain of 23 (Feedback loop is a 22k resistor, with 1k to ground), and the preamp section has a gain of 2. How much gain does the average plate amp (Say a 300W into 4 ohm one from PE?). How much of it is in the amp section, and how much is in the pre-amp (gain circuit)?? If anyone has schematics, that would be great too, although I only need the gain amounts. Pics of my sub will follow in the New Year as soon as I get hold of a digital camera!!
