Hi Krisfr
The circuit diagram is hard to read – any chance you can re-post with higher resolution?

post 386
On post 386 there is a mistake around positive supply of input stage .... dont build as-is

That error is on the schematic, but not on the board, thankfully.
The C and E of T3 are shorted!

Sir Jojo,
I Ronald Here also in Phils, did you buy those parts here locally? Its seems hard to find.

Hi Ronald,
Mouser, RS and Farnell has them, shouldn't be that hard to find. Beware of some locally available parts, especially the active devices, lot's of counterfeit stuff out there.
Most of the active devices available out there can be used for this amp, you just need to check Vce and their pin orientation. Of course, OS's recommendations still stands since they were chosen for their performance.

Sir Jojo,
Im intersted with your work. Can i buy ready made pcb with you? I have original output trainis from onsemi but no yet circuit for my amp. Pls PM me your personal mail. tnx.

Hi Ronald,
The boards will be exclusively available at the diyAudio Store after we've tested it and tuned to our specifications.
Hold on to those trannies, once this baby rocks then I'm sure you'll have an excellent excuse to use those in your arsenal.

The PCB layout program sometimes changes the coordinates of trace points, when I duplicate the board. I dupe the board to save a version.
I have corrected the noted problem...
I am very busy with another project at the moment, I will post more readable visuals shortly.
Thanks
Here you go...
Please comment correct or otherwise, I want to get this right... and I am open to suggestions for improvements too.
I am willing to share this with anyone that wants to DIY.
It, the board is NOT done, I have to mark the parts on the ground plane. I think it can be made with one side with jumpers. I will strive to make it doable one sided.
Also the schematic for the power additions are just what you need to add to OStripper Schematic...

Krisfr, is it possible you can make the text cut out of the ground plane, instead of having to clear space around it? Seems like something sensible any layout program should be able to do.
D104 and D201 still need to be reversed on the schematic and the board.
It looks to me like the input stage CCS is all foobar'd.
