The data sheet of the TL026 doesn't mention the maximum input signal that can be

processed. For the SL612 that is 250 mV rms.

Actually, the datasheet mentions it - ~200mV.

With so many data sheet archives online, I could have hit the wrong one. But
what didn't fail to get my attention was the remark "Other Characteristics
Similar to NE592 and uA733". With those ICs I'm not only familiar but they are
from the era when customarily, the equivalent internal diagram was published so
uninitiated application engineers could use the IC in a fashion, not intended by
the designer. The NE592 and uA733 employ negative feedback which is at odds with
voltage controlled gain - unless the gain control is before the stage(s) with
feedback, and then the S/N under application of feedback deteriorates.
So the TL026 isn't my choice even if it's modern ;-)
