Thanks Matthias, I appreciate the reply and reassurance.
Interesting <br>
about the TL064, I've never heard of the chip before. </blockquote>

<div>Oh, I thought the "precision" TL05x series were the
unknown ones in the family. :-) (Does anybody use them?) The
TL06x are the low-power ones, and the TL07x & TL08x are
the twins separated at birth that nobody seems to know if
they are identical or not.</div>

<p>I've used the 054 in the past. But it is difficult to justify
that choice and the extra cost. <br>
</p>
<p>There is another member of that family that I think nobody has
mentioned so far. The TL03x. The "better" TL06x. Low power, lower
offset. <br>
</p>
<p>Much like the TL05x is to the TL07x. It think they were
introduced at about the same time. <br>

<div>It's a bit annoying that op-amps often need much more
current just to function internally than they deliver to the
outer world even at full force and heavy load in our typical
synth circuits. :-)</div>
