what is the frequency response of this amplifier
DC-40kHz without input cap.
Use SR200 for PA speakers and share your expirience,
Regards
Hi! Mile
please confirm me again whether it will work for pa applications??
or i will get oscillations like b500?
so that i can buy parts and start building.
i need an amplifier which is more durable.

I suggest you HV23 http://www.diyaudio.com/forums/solid-state/162043-mosfet-amplifier-irfp240-irfp9240.html
Nice work, thank you for share this pcb design,
Regards
Drawing layout is just something easy,many people can do that, but design a very good schematic is something difficult,need many years of experience and complex math like what You've done.

Hi! Mile
can i use bjt instead of mosfets??
mosfets are too expensive here
Hi Reski,Bottom will be upload later.
the size of PCB please?
Very nice just like layout from apex 😎 , what software do you use?
Hi comasus,can i use bjt instead of mosfets??
mosfets are too expensive here
That IRF240/9240 is not too expensive, I bought it here cheaper than SanKen bjt transistor

I suggest this amp with BJTs, and you don't have any stability problems

I have already tried this amplifier but not satisfied with that sound you can see my comments in that thread
ASK
Hi Sir Mile, apologize in advance this might be a silly question and beyond the discussion, can I use this schematic for power supply with an output capacity of 48 Volt 10 Ampere? whether there are components that should be changed or added? please help me. I needed.
Thanks. regards Damanhuri.

Use single 50vac instead 2x65vac, and 15V zener instead 20v.

Thanks Sir.
This amplifier works only for studio speakers (high quality speakers)???
This amplifier works with any speakers

what is the special in it when compared with ax series?

There is nothing special just different amp topology with DC servo.

Dear Emmi..
Both of them are very OK, but in my experience I prefer SR200. But considering at my financial budget I like AX series or SR50. The fine 10 uf MKP caps are very costly in Indonesia.
Those amps are much better when using regulated PSU, imho.

Arif

Thank you
can i use this for monitoring overall sound in outdoor use just like pa ?
Have you placed all the jumpers? There is one in a lower left corner under the 2k2 2W resistors,easy to be forgotten and overlooked.
Thanks for reply, yes i have done all the jumpers maybe there some error in my pcb traces or parts that need to replace.
