You may wish to consider it, also. Carl, NM1H, has developed a SB-200 parasitic choke replacement alternative that works effectively. Ken, W7EKB, built and installed Carl’s design. According to Ken, the new suppressors do the job very well keeping his SB-200 cranking out the power with no parasitic problems. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Since I haven’t yet asked either for their permission to share their recipes, you may wish to contact Ken about his pictures.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Good luck,<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Chris<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>W7JPG<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> heath-bounces@puck.nether.net [mailto:heath-bounces@puck.nether.net] <b>On Behalf Of </b>John King<br><b>Sent:</b> Wednesday, January 09, 2013 6:44 PM<br><b>To:</b> Heath@puck.nether.net<br><b>Subject:</b> [Heath] SB 200 Parasitic chokes<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal style='background:white'><span style='font-family:"Courier New";color:black'>Has anyone changed the parasitic chokes on their SB 200s. I need to change mine because the leads to the chokes are breaking off at the resistors. Has anyone tried chokes made width ferrite beads on wire leads as parasitic chokes? If so how many beads and what mix and size? The 47 ohm 2 watt carbon composition resistors are not available locally and neither is the tinned wire to wind around them. The area around the tube plates doesn't leave much wiggle or working room. What has been your experience with the SB 200?
