Stereo amp (tda 2030) with pre-amp(jrc 4658)

This is the testing stage of a mono amplifier using: one TDA 2030 IC,three 0.1 microfarad ceramic capacitors, two 22k ohm resistors,one 680 ohm resistor, two 220 microfarad electrolytic capacitor, one 1 microfarad electrolytic capacitor, one 22 microfarad electrolytic capacitor and one 2.2 ohm resistor . The circuit is working perfectly. The final work on veroboard will be posted another day.

During my secondary school days at technical college, building of audio amplifiers most especially using TEA2025 was something everyone wanted to do. But then, I had zero idea on how to build one but at least I could read a circuit. The first circuit I built was on a ceiling board using TDA2030 and it failed. No output from it. It was from there I had the courage to start building circuits until I was able to build a working one. And today, I can build an audio amplifier with (Transistors and IC). Hard work and consistency brought me thus far.
