Ok during my spare time in the office I made a rough draft for my SR200, Miles let me know your toughts about it.
BR,
Junie
What is S4?
my first SR200, use layout from Mr.Alex.
thanks Mr.Mile and Mr.Alex.....
Nice work, what about sound?
...... sorry , was modified so many times ..... forget to make connection but the silk screen it's the same . In the post#707 it's correct ......
Alex.
Hi Alex, what is the difference Between SR200 v3.1 and The very first Sr200.
there have been lots of SR200 Builds. This Amp sounds good with pretty Standard parts.
Why not give some advice to use best of the components and make this amp more better sounding.
What changes are necessary to play this amp stable at 2ohms.
can any one post layout for stereo protect.
What is S4?
S4 is a soft start by Ostripper.
@ mas Arif , thanks mas Arif, regulated power supply for next project.
@ Mr.Mile , sound very clear for my tradisional music and for progressive metal.
Can you post link to Youtube for this music?

What is your speakers?
Under torture!
An externally hosted image should be here but it was not working when we last tested it.
What is your rail voltage, bias seting and DC offset?
Hi joe,
I noticed in your PCB that instead of Jumper you placed 1k 1/4W resistor, why is it?
Thanks,
Junie
hehehe..... it looks weird
only to test,because at first mje350 error.then i use R 1k, for safety over current.
Hi Miles,
Supply Voltage: +/- 68V
Bias setting: not set yet I have a wrong resistors value, will sort it out tomorrow
DC offset: varying from .1-5 millivolt
Please suggest bias settings for three pair output with mentioned supply voltge. Thanks
Junie
Your heatsink is too smal, set bias 100mA max for 3 pairs (30mA per pair)
