[QUOTE=georgi.g.zhelev;177320]mohandes your PCB IS VERRY BAD DESIGNED , R20 directly to pin 3> pin 6 ; D3,D4, directly pin 3 > GND; C13 directly to pin 1>pin 5 ; R19 directly pin2 >GND. OK

this is not my design georgi,
if i find op27 can replace by ne5534?

I just read this whole thread, word for word and looked at every image and feel absolutely mentally drained an physically exhausted...... I think I need a couple valium now just to slow my brain back down to normal....

All kidding aside, you guys are awesome for all the help you passed on here and I surely hope mohandes got it figured out and working good.. that was one helluva project with some serious communication deciphering.... hats off to you all and mohandes for some project dedication and perseverance...

Thanks for the educational thread,
