can i give +/-48v to this circuit
what i have to change in the circuit diagram
if anybody have pcb you can send it to me at mounicashreya@ymail.com

NO! Vceo is on the "hairy edge" for those devices (BCxxx BDxxx) , amp can only take + - 35v .... safe at 30-0-30VDC. Tip outputs are only good to 80V rail to rail. Might work for a while , then POOOOFTTT!

TIP35C/36C are 100V VCE devices but the drivers BD139/140
are only 80V.
Strange thing is the use of BC559 for the differential.
They are only 30V vce..Better to use BC556B devices...

Hi,
a 3rd no, just to convince you that this schematic using low voltage devices is intended for use with a low voltage PSU. Probably +-30Vdc to +-35Vdc.
Expect maybe 50W into 8ohm.

This an ESP design. If you want the PCB you'll have to buy it from him < 100W Guitar Amplifier (Mk II) > . He makes his living from these designs so it would be unfair, immoral and possibly illegal to spread the pcb layout around.
