Dear,

Please give us some more information I don't want to break the joy, but NE5532/34 are not the right opamps for a DC servo since they are not FET input amps. The TL072 would be a better choice.

Any schematics pictures?

With kind regards,
Bas

yes i will post every thing once when i am free but basically the design is from LM3886製作的純直流功率放大器 no alterations what so ever and every thing is same except for some resistors which i could not get as precised from the local market and all of them are very near values to the original values in the provided schematic, thanks to he said site.
I will post all the images and related material very soon

thanking all
