I built the tda2003 according to the bug eye schematic. First I used 3 2n5088s for a preamp. This worked decently, but I feel it wasn't Lou d enough. 4 transistors made it clip and cut out real bad.
I then built the pre amp with a singe mpf102, volume was about the same but less feedback.
It seems my lm386 builds might actually be louder. Both are equally clean I'd say.
Now I have switched my power supply to a lithium ion setup pushing 12v at 4.8amp peak.
Now from what I'm reading, I need to use my lm386 set up to power this thing. I currently have them bridged on 12v also. This chip is maybe 5 degrees more than room temp.
I'm thinking(no idea) that the lm386 set up would drive this thing to the point of failure. 4 transistors made the sound go from clean to popping inexistance.
