[sci.electronics] 4739, 4136 op amp substitute - help needed in choosing

abs@ukc.ac.uk (A.B.Smith) (01/21/91)

Hi,

I have a book called 'Electronic Projects for Musicians' and it uses the
4739 and 4136 op amps. I am having trouble finding a convenient suplier
for these and am wondering how I go about choosing replacements. I am
not interested in pin compatability (and using two chips for a dual op
amp is not inconvenient).

I have found other audio op amps that have lower noise characteristics,
can I just replace the chips with these. What I don't want to do is mess
around with resistor and capacitor values (as you can see I can only
manage to build the projects, I know nothing of analogue electronics!).


Many thanks,

Andrew.
