D3, D4 & D5 can be signal diodes 1n914/1n4148 or rectifier diodes 1n4001/2/3/4/

What are the voltages across
R16
R17
R18
R23
R24
R25
R26

Are R19 & R20 swapped?

Do Q8, Q9 & Q10 get warm or hot?

R1/C2 ? F-3dB ~ 5MHz!

Is the gain really +48.4dB? 58k/220r +1

i cannot test yet the voltage across R16 to R26..
so Q8 Q9 & Q10 is warm it is a normal..
however the amplifier is work sound good and clear but the problem when
the volume is higher more than mid position distorted sound but volume is not a full power...

Is the gain really +48.4dB? 58k/220r +1 so What do you mean ?
Are R19 & R20 swapped? ok tmrw im veryfied the circuit if im wrong hehehe
may you help ... thanks Andrew T.

if the posted circuit is still wrong and you are laughing at that possibility then I am not playing.

Actually the amplifier is work... when i replace The Value Of R13 C5 the sound distorted and now ommitted the local value back to the orig of R13 C5... before upgrading the amplifier.. . i replace it because im not a satisfied seems so weak.the amplifier when i used to drive 18inc. w-box subwoofer in my sound system. so i need to upgrading the amplifier. may you help.
