In Reply to: stability of 637 posted by Ehien on January 31, 2002 at 09:33:53:
Hello again Ehien,I'll try AD826 against 627, but it will take some times. I'll built a newer phono stage soon to incorporate the 50KHz pole and will go full monoblock, batteries PSU too. And no, I wouldn't buy the LC Audio soon, I have enough of op-amp here, there's no way I will pay someone to do a job I can do. But for begginer, the LC Audio solution is easy.
Me too, I prefer BB over AD equivalent. And I've only seen one BB chip going bad so far. AD is not bad, but doesn't give the same MTBF as BB.
Stability have more to do with PS lines than feedback. In my basic design, the OPA627 oscillate. I will fix that today and include it in the match.
Regards,
Daniel Trudeau
