Op Amp question

[Tim Curtis]

Hello Everyone -

I have a couple small quantities of Op Amps around here that I'm not too
familiar with - can anyone tell me what common parts they're a good
substitute for?

One is a 5534 - I use the 5532 all the time, is the 5534 similar?

The other is a 4570C.  I'm not familiar with this one at all.  Same
series as the 4558 perhaps?

Also, I have a Minimoog Oscillator board here with a bad TL081 on it.  I
can't find one in town anywhere.  Is it possible to use a 741 or
something else in there temporarily?  Any Suggestions?
