using the said chips the dc servo amplifier has been made and it is indeed excellent
yes i will post every thing once when i am free but basically the design is from LM3886»s§@ªº¯Âª½¬y¥\²v©ñ¤j¾¹ 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.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,
