Audio Preamplifier Circuit Diagram. Any music as we know is in the form of a consistently varying frequency therefore when such a varying input is applied across the indicated c1 end terminals the same is delivered across the base t1 and ground. All capacitors with value of 33uf are 16v while the all others are 50v unless marked otherwise.
The low noise is one of the main characteristics of this circuit. This circuit is little hard to built. Phono preamp valve microphone preamplifier.
