Question Apex, is this an 8 ohm only amplifier? if not isn't PSU filtering a bit small ?
regards
Why do you think 4x10000uF/100V per channel is to small?

.....I have try to layout PCB for SR 200 V2 but it's difficult to do sigle sided ...
Thanks for try 15k must be connected to +15V not to +Vcc...
..... Revised PCB this time , much better I hope ....
Alex.
This pcb can be use, what is the size? BC639 can be use instead BD139, and only need 5mm hole in heatsink for TO92 case.
Regards
..... size of PCB it's 162 mm x 65 mm .
Regards Alex.
DID U MADE THE AMP?
WHAT IS HE OUTPUT POWER?
POWER SUPPLY
thanks.i will try find this numberTHS4131 is pin-to-pin and functionally compatible with OPA1632.
Hi ,
negativ , I don't ,but in change here it is another PCB with output BJT in line
Regards Alex.
Nice pcb again, bases of 2N5401 in diff cascode must be conected to -15V (pin 4 of LF411).
Regards
Revised PCB .....

Hi apex!
Can I use this amp to power my JBL GT5-12 (275W 4ohms)?
Thanks
Yes, you can use +/-65V rail voltage for that power,
