guys.. .help namn po.. .cnu may circuit sa ineo ng power stereo amplifier 140W tpos 70W per channel na may supply ng 50Vdc.. .ung simple lng po.. pure transistor lng po.. .aun.. tnx sa mgrereply.. .in need lng po tlga.. sana may makatulong..

.. and kapag mgcocompute po ba ng critical frequency kelangan po ba lhat ng capacitors ay icoconsider??

.. sa power amplifier papuntang dividing network up to the speaker system.. kelangan din po ba na may impedance matching???
