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.

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></span><span class=""><div> <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;text-align:-webkit-auto;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;font-size:medium"><div style="word-wrap:break-word"><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;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px"><div style="word-wrap:break-word"><div>Terje Winther</div><div><a href="mailto:terje.winther@wintherstormer.no" target="_blank">terje.winther@wintherstormer.no</a></div><div><a href="http://wintherstormer.no/" target="_blank">http://wintherstormer.no/</a></div><div><br></div><div><br></div></div></span><br></div></span><br> </div><br></span></div><br>_______________________________________________<br>
