Thanks Apexaudio!
The reason why i'm simulating the circuit is to find out how it would perform in real life situation. So, this would only mean that the amp is inverting the signal and making it out of phase if it has the limiter circuit?
Signal input using point A to S-gnd is jut like running the amp without the limiter as suggested. It gave me no output signal. How about configuring the limiter circuit as a non-inverting input stage?
Thank you again for your assistance!🙂
Hello apex,
What the exact value of resistor of R24 and R25 i put?
I have a 47v 0 47v ac toroidal and measure -65v 0 +65v dc..
i bought
4k7 2W = 2pcs
2k2 2W = 2pcs
3.3k 2w = 2pcs
Thank you so much for your reply. Your design have a clear and fantastic sound quality. 🙂

sir apex i saw in b500 schematics there are two ics ne5532 . in the pcb layout only one have . what is the point.
Naz,
divide by your supply voltage.
If your supply is 110Vac and the transformer is 110Vac 700VA then it can be specified as 110Vac 6.6Aac in the primary.
Rarely do we see primary current ratings.
More usually we see secondary current ratings.
This time the primary voltage rating must suit your supply voltage and the secondary would be specified as 110Vac:40+40Vac, 700VA or specified as
110Vac:40+40Vac, 8.75Aac each secondary.
You have to do the arithmetic to suit your voltages. Use VA = voltage * Current

i cant understand andrewt .my primary voltage is 220vac and secondary 55,0,55v so how much ampere after calcutaion comes.
secondory current=700/ (55+55=110)
this means 700 devide by 110 am i corect?
so the answer is 6.363ampere is it corect?

Can you post pictures and describe problems. Step driver is 'CROWN' schematic, TL072 work as comparator circuit is simple...
I try to apply this....

sir apex check the connection if correct.
