without transistors one side had 40v other like 6 with them like 28 and 7 so one side does not have power or whatever
this is audio that i get maybe it a bit louder in person but its really close.
without transistors is not sound this time maybe because i added those resistors i dont want to remove them rn

btw if i get it just right i can hear clean sound, when i dont add too much input signal but it should not work like that
also sometimes i can hear in low volumes that its like if is not grounded maybe it is not i am not sure
What do you mean with 'one side' and 'other side'? what are you measuring? If the supply voltage is 55 volts, you should measure from the mid point of the amplifier (wich is + terminal of output capacitor) to ground about 27.5 volts.
Your measurements do not add up to 55, so I don't understand what you are measuring...
btw bulb now is not as bright as yesterday, i was reflowing all traces maybe it did something. so from now on if you guys can tell me if something specifically is a problem i will check it i spent a lot of days like 7hr a day messing with this xdd
Without a signal at the input, this 1.5 ohm resistor should have a voltage of 75 mV.
Look, is there?

Where? Where? The resistor is 1.5 ohms.
Where else? 🙂
For example, in schematic R7.

I listened to the recording and it's distorted. What are you driving the amp with? What is connected on the input?
A cd player, a smartphone, a PC line output?
Please measure the 3 points indicated, with your meter on DC voltage.
1 & 2: across both resistors with the wire. R6 and R7 on the schematic.
3: across the two other ends of the resistors.

i used phone. but that does not matter at all it should have power if transistors are really working 😀 it is trying thats for sure xd btw what should i expect ? what kind on voltage there ?
