[sdiy] njm4560 op amp replacements

[Steve Lenham]

The NJM4562 (still available from Rapid) looks v.similar but is only 
compensated for gains >10, which may or may not be a problem in your 
application.

Or, if you can justify buying 25 or so, the 4560 is available from Profusion 
(http://www.profusionplc.com).

Having said that, the 4560 is only (their words) an "improved 4558", so any 
half-decent bipolar opamp should be an OK replacement. I rather like the 
OnSemi MC33078/9 (v.good audio performance) and MC33178/9 (good audio 
performance and low quiescent power - a nice alternative to thirsty 
NE5532s).
