I need to knock up some stereo (domestic) line level amps with a gain of
0-10dB.
Using a +/-15 volt supply. Anything better than the ol' NE 5543 for this
these days?

The ole 5534 and 5532 are still very good and easy to use for that sort
of app Dave...

The 5534 is a lot better for that than the 5543.

FWIW I always preferred the Hitachi 12017. But I realise that this is a
somewhat unusual choice. :-)

Slainte,

I think the 5534 is still about as good as it gets. There may be
something around that measures a little better by now, but nobody
could tell by listening.

But I'm going to use it with +&- reversed...

NE 5532, because you get twice as many op amps for the same $1.

Looks like it is purpose developed for RIAA preamps.

It seems to be happy with somewhat higher VCC.

Reading the data sheet, I see no info about one of the NE5532/NE5534's long
suits, which is low distortion into low impedance loads.

Yes. That was the intent of Hitachi. :-)

However experiment showed that with suitable tweaking of the stabilisation
network it works nicely as a buffer of voltage gain stage.

Yes. IIRC I used to use it with +/-20V lines.

Reading the data sheet, I see no info about one of the NE5532/NE5534's
long suits, which is low distortion into low impedance loads.

Afraid I can't recall all the measurements I made. But the specs for the
Armstrong 732 showed I got less than 0.005% 20Hz-20kHz into the 10k IHFA
load. For up to over 10Vrms IIRC.

That was of course going though more than one 12017. I think it also worked
fine into much lower loads than 10k provided you didn't ask for +/-20V. And
I think it was OK down to about 1k load provided you only wanted a volt or
two. But I can't now recall details. Certainly at the time I preferred it
to the competing op amps.

I guess most people never considered trying it as a general amp due to the
presentation being for RIAA. But I noticed the high rail, low noise, etc,
and found it responded well to being experimented with. Hence came to
prefer it.

Slainte,

Jim

For that gain range I'd use 5532s as they are fully compensated and thus
work down to 0dB gain without external compensation caps. The 5534 is only
stable at gains of 10dB and above without external compensation.
