mmmmmmm ok it looks like the T from LMT is from texas instruments, so i think they give me a bad replacement component.
Maybey there are some people who knows a litle more about this one in a denon amp, and de sound improvements of this thing. regards Rick... |

Hi WaHab, after searching on the internet, there was no any datasheet about de lmt2904n, si i even think it`s a low performance lm2904
The T from LMT stay for texas instruments. So i will return this bad op-amps. I listen to you and have deliver de opa2134pa as a better replacement of NJM2082D. I hope this will sounds like a charm in this amp. Do you have experience with the opa2134pa or are there other people here on DiyAudio who know more about de quality of this op-amp. Regards Rick...

without seeing the part of the schematic that use this device, it s impossible
to be affirmative...but at first look, the OPA2134 is better than the NJM, at least in the GB product, so assuming it s stable, it will surely give good, if not better, results... regards, wahab |
