JRC7031substitute

[glasspak73]

can anyone tell me what substitutes will work for the ic JRC 7031D on the way huge fat sandwich circuit? I can't find a data sheet on the JRC 7031D

The JRC7031 is a CMOS single opamp and I haven't come across them very often and so am not sure if there is a more readily available alternative using the same technology.  But the schematic I have suggested using a TL071 as an alternative so I'd go with that (or other common single opamp of your choice).
