Assemble Mini Power Amp TDA2050

Maybe anyone want assemble a mini amps for rooms audio? IC-Amp TDA2050 maybe this one can be a choice. besides the price is very affordable as well sound produced can spoil our ears. said the IC-Amp TDA2050 one is a rival LM1875 (though still better LM1875). This circuit scheme and pcb layout :

Power amp output 30W,with VCC around 18vdc 2-3 Amper is enough for the speaker 4 "-6". although mini power amp but have good sounds.

Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.


Dear Sir,
Kindly let me know the transistor numbers of Q1,Q2,Q3,Q4, and Q5 of of the 300 watt amplifier circuit given. These transistors are given on the PCB layout for the speaker protection with the relay.
kindly reply on

Dear Sir,
Also let me know the positive & negative pins of 22UF condensers used in the speaker protection circuit.

Can you comment at the circuit you asking?
