Hi, I am trying to use an old Sony hi-fi speaker as a guitar amplifier using an audio amplifier circuit with the TDA2030 Hi-fi amplifier.
I have been trying to find out how an input jack is connected to the input of the circuit but I can't find anything. I have attached a pic of the input jack, the lead used from guitar jack to the circuit jack and the amp circuit.
Does anyone know what the 2 solder lugs do and how they are connected? and also is this feasible?
I simulated the circuit on Proteus with a 10mV sine wave and it amplified the signal on an oscilloscope and produced a sound on the loudspeaker model.
I'm not sure of the amplitude of the signal from the guitar and if I will need a pre-amp before the audio amp.
