It's no problem to replace an TL06x by TL07x or TL08x. In the first A-100
modules we wanted to keep the power consumption as low as possible and
therefore predominantly TL06x were used. In all newer designs the TL06x are
mainly used in CV paths. In the audio circuits TL07x (or others like NE5532,
LFxxx, OPxxx).
