Here two problems in my work
1, Sir u right my psu capacitor bad some time they produce hum or little sound. Now I change them with 15000uf/80v best brands.
2, As I say in last post I m rookies, I use wrong resistances because value on resistance r blur. Likely A Diy member
(Who come in my city for business reason) he contact me and check the board then we noticed we use wrong resistance. I replaced all these resistance, now amplifier working superb. I feel very sorry with my little mistake we disturb u so many times. But with ur experience amplifier working fine.
3, one more thing we just play the amp with 100w series load in main supply, any suggestions before removing that load. Sorry for my mistake and Big thanks you and Mr Miles depth from my Heart.
Regards
Sunny
Finally sunny u taste the piece of cake.Congratulations 😤
Here is my PSU unit now
Wow 😲 nice in next trip in ur area these capacitor is mine😃
Mr.vargasmongo3435 please tell me and sunny which Preamp or buffer use with SR200
Regards

there is one that Mr. Alex MM made the PCB layout I don't remember the post number sorry is been so many new designs I lost track lol
Hello .Sir can I use MOSFETs on sr200
I think it can be done but the circuity might change a lot to accomdated mosfets I would't changed
Sound quality is too good sir but need power. Then sir what I do.can u increase power

simply because you have had a cat , dont make it a dog. Check out FR100 by Mr. Mile in this thread.

Go to SR300 or SR800
Go to SR300 or SR800
Greetings my Lords .But u say it's for commercials not diy (sr800) sry for my bad English

hello guys I want to keep it all about the Apex SR200 subjet I need to ask a question Mr. thimios add this components to the his build I have a copy layout from Mr. Alex MM that I save for a long time I add thimios's cap 18pF to the layout also a 100pF cap too, I have every single components identified too, are this componetes placed correctly?
Note: this is Alex MM's design not mine I just like it so much that I copied lol
I know this a long time project that I haven't try yet but I want it to be sure all is correct before I order a few PCB to try out

Sunny check how much power you have measure using a dummy load of 8 to 4 ohms and to se how much power you got the design should give around 150W or more check post How to measure Wattage of an Amp #2 if you still have probles check feedback resistor maybe you place a wrong value I mean it can happen to all of us when we are in rush
