I used the metal can LF356, which can easily be bent to replace the FET follower on the existing PCB.<br></div></blockquote><div><br></div>Indeed! The PCB and front panel set I got came with some original NOS parts, so I used them where I could, meaning I had to do the necessary work to make them function properly. In other places I had to substitute newer parts, and the upgrades described in book 2 was really useful in that regard.</div><div><br><blockquote type="cite"><div>As said by others, first find the parts you need, only then build it.

For several of the modules I needed to build small test-circuits on veroboard so I could select correct transistors, diodes and ICs, and for some of the modules it is a fairly specific way of adjusting the trimmers or even finding the correct value of a resistor, involving desoldering parts, shorting out components and connections and the like. Quite doable, of course, and everything is very well explained in the book, so even though it is a little more work than on contemporary DIY modulars (which are easier to build and works pretty much straight away), it is mostly fairly easy to build these modules.<br></blockquote></div></blockquote></div><br><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>Terje Winther</div><div><a href="mailto:terje.winther@wintherstormer.no">terje.winther@wintherstormer.no</a></div><div><a href="http://wintherstormer.no/">http://wintherstormer.no/</a></div><div><br></div><div><br></div></div></span><br class="Apple-interchange-newline"></div></span><br class="Apple-interchange-newline"> </div><br></body></html>
