NE5530N op amp or substitute?
 
Hi,
I have an old QSC a32 I might have posted about previously. I'm still looking for a sub for NE5530N. Or if anyone has one or two and can do paypal that would be even better.
This amp is good to go except for this one part! Anyone?
QSC has told me ne5532 would not work?

Schematics :
http://www.qsc.com/support/library/s...ies/A31-32.pdf

NE5532N have two internal clamping diode. (on differential input)

I have looked for datasheet of NE5530 but is cannot be found.

NE5530 can perhaps be replaced with a NJM4560

Compatibility with pin - ok (from schematics)

From schematics supply originates from 1N4744A = 15V zener

Also I have seen that in all the new schemes QSC the NE5530 has been replaced with the NE5532...

I have to wonder if the 5530 was a house number. I just looked through a bunch of old databooks, and can't find any reference to it from any of the people that made NE/SE prefixed parts.

some retailers say that the NE5530 is production of Philips.
at this point I think that is better to ask directly to QSC

tech_support@qscaudio.com

to ask Replace/substitute for NE5530 or datasheet ! :D

bye :)

QSC just said that it was obsolete and wouldn't suggest any subs. I'm still learning to read and compare specs on ops,so I'm not sure about finding something suitable. If no harm would come in trying the above models I would be more then happy as I have most except the AD8066's mentioned. Which I am going to see how available they are.
Thanks for all the help!

You said first thaat QSC told you NE5532 wouldn't work, now you are saying they just said the NE5530 is obsolete. Which was it?

I would think that NE5532 would work.

I was replying to gold and others. QSC said 5530 was obsolete(and they are unless you order from the $300 minimum warehouses) and told me 5532's would not work. They did not make any suggestions as to what would,simply saying save yourself the hassle and buy a PLX.

I got this thing working 99% and all I need is one stinkin op. Besides matching pin outs there's not much I can tell from spec sheets. I'll try some of the above suggestions,I just don't want to ruin my work and short a channel or think everythings fine because the amp seems to be running and then have it fail later. Thanks again for any input!
