My first soldering job was on a KnightKit C-100 CB walkie-talkie in 1965. The instruction manual suggested using a metal, spring-loaded hairclip as a heat sink when soldering the transistor leads.<div><br></div><div>73 de&nbsp;</div><div>Gene Smar AD3F&nbsp;<br><br><div id="ymail_android_signature">Sent from my Radio Shack TRS-80 model 100 laptop</div> <br> <blockquote style="margin: 0 0 20px 0;"> <div style="font-family:Roboto, sans-serif; color:#6D00F6;"> <div>On Wed, Jul 30, 2025 at 2:41 PM, k2cby@optonline.net</div><div>&lt;k2cby@optonline.net&gt; wrote:</div> </div> <div style="padding: 10px 0 0 20px; margin: 10px 0 0 0; border-left: 1px solid #6D00F6;"> <div id="yiv5521228455"><style><!--

Unless the values were extremely high, they were probably wire wound.</span></p><p class="yiv5521228455MsoNormal"><span style="font-size:11.0pt;">Second, you can solder a resistor – or other component – without altering its value by gripping the lead with a hemostat next to the body of the part.</span></p><p class="yiv5521228455MsoNormal"><span style="font-size:11.0pt;"> &nbsp;</span></p><p class="yiv5521228455MsoNormal"><span style="font-size:11.0pt;"> &nbsp;</span></p><p class="yiv5521228455MsoNormal"><span style="font-size:11.0pt;">Miles B.
