That’s about THE most common op-amp configuration. You must log in or sign up to reply here. No – the is a dual op-amp. Share This Page Tweet. The National LM is a great chip. Anyone have any info.

In the phono circuit some real oldies, uPCC’s, u is micro I cannot find any info. No, create an account now.

Thanks for your help guys. National Semiconductors LME49xxx line of op-amps have very impressive specs, but I haven’t datxsheet them out yet The other two, NJM are close relatives of the NE, one is used for tone control and is bypassed when these controls are not used.


But does much much better from about 1kHz up for Distortion, noise, separation In any cese, if there is one to be replaced, this is the one look for it between the two blue bands that drive the tape loop and record 4558d selectors. Its sounds very clean, clear and detailed in mid range up.

I just upgraded my Entech dac to the LM and put some film bypass caps on the supply rails GibsonianFeb 3, I would like to compare. GibsonianJan 28, Personally, I prefer Texas Instrument’s Excaliber series. Yes, my password is: Mystic PixelJan 31, Do you already have an account?

The LM does better through out the Freq range.

I use it as a drop in replacement all the time for the More clarity, just as much bass but tighter. I have recapped an older Denon PRA preamp and am hoping to replace the opamps inside to further improve this oldie but goodie.


I’m not too surprised by your findings. The bar continues to raise, which is good for the ears. I was reading the specs on both chips.

Any of the plastic bodied DIP’s in this group will work? How about spec sheet on the C, know of where it can be found? GibsonianJan 29, I was surprised at 4558dc difference at first, until Dataxheet read the specs, then it all made sense That is my opinion of course, you may want to compare a few to get the sound you like.

Let me know your results, I may want to experiment with the LM as well.
