Circuit building: stop using antique parts (2014)
There&#x27;s still plenty of reason to use discontinued components in DIY. And that reason is the form of the component&#x27;s package.<p>This is a problem for me when building high end audio circuits. A lot of the modern components are only available in surface mount forms. I find this with matched transistor packages. Like a matched quad. There are modern components, like AD&#x27;s MAT14 [1], but if you are building your own circuits and using through hole components your ONLY choice is discontinued components. They simply are not made in a through hole package anymore.<p>At some point I&#x27;ll be forced to move to surface mount, but at the moment getting old components is a lot easier. And those old components are as good as the new ones. Just different packages.<p>If anyone knows of a modern precision matched quad like the MAT14, but in a traditional package, please reply with the component!<p>[1] <a href="http:&#x2F;&#x2F;www.analog.com&#x2F;media&#x2F;en&#x2F;technical-documentation&#x2F;data-sheets&#x2F;MAT14.pdf" rel="nofollow">http:&#x2F;&#x2F;www.analog.com&#x2F;media&#x2F;en&#x2F;technical-documentation&#x2F;data-...</a>
