I am using low power transformer , could that be the reason.
I have checked the tracks continuity, Its fine.
whats the voltage you used?
whats the voltage you used?
24-0-24 3 amperes, after rectification it is 37-0-37.
Maybe fake, some transistors?
not at all, all are original toshiba trannies.
post some more pics bro....
Check the pics and guide.

The sound is very low and distorted.
The resistor 0r22/5w in front of 2sa1943 on psu board got burnt .
My psu 24-0-24 before rectification, after rectification 37-0-37.
I can't see input ground to PSU did you follow this?
Yes i followed the diagram. connected the psu gnd , input gnd and out gnd at a common point on gnd next to out
Hi Apex. i have a problem with your amplifier.
It all looks ok when connect him, and play song. But when volume reachs half, speaker starts broming(brrrrrrrr) very loudly. I turn off amplifier, reduce volume and and turn again on, and all looks again ok. Where is the problem? Please help me!!!!!!!

did you test MJE340/350 and 2n5551,5401 unmount it on the pcb then test it with multimetervoltage on negative terminal drops to 20v, after connection to b500.
positive voltage is proper at 37v.
I think you mean 33E = 33r = 33ohm resistor.U use 33E or E33 for emitter?
If that is the case, then E33=0r33 = zero point three three ohm resistor.
Do not drop the leading zero. It is important to accurate transfer of information.
