The previous generation 2400 do have a basic SM with block diagrams and parts list; one can assume the 2600 wasn&rsquo;t redesigned from scratch but they are certainly very different.</p> http://www.qcte.ca/testeq/k2600/pics/ Sun, 19 Apr 2026 11:07:07 -0400 http://www.qcte.ca/testeq/k2600/pics/ <p>Right-click + &lsquo;open in new tab&rsquo; for higher resolution.</p> <p><img src="http://www.qcte.ca/img/k2600/unit%20back.jpg" alt="unit back.jpg" /> <img src="http://www.qcte.ca/img/k2600/mainpcb%20top.jpg" alt="mainpcb top.jpg" /> <img src="http://www.qcte.ca/img/k2600/psu%20top.jpg" alt="psu top.jpg" /> <img src="http://www.qcte.ca/img/k2600/psu%20bot.jpg" alt="psu bot.jpg" /></p>
