Kits are available for both<br />but in your case I think, I would check the functionality of the electronic switch and especially<br />the little IC9.<br />Check also for cracked solder joints at the large output stage transistors.</p> <p>Martin</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/249660.aspxFri, 01 Jan 2010 17:45:53 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:249660strangeadam0https://archivedforum.beoworld.org:443/forums/thread/249660.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=30&PostID=249660<p>when i try to start the ic responds with a change in voltage but it doesnt seem to hold. </p> <p>If i sortsircuit the relay and touch the pins is flashing the diferent bulbs but there is no signal to amplifier from radio and when i remove my hand the bulbs go off. In this condition the amplifier produces a noise when i put a finger on the transistor.</p> <p>thanks anastasio</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/249648.aspxFri, 01 Jan 2010 16:36:43 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:249648Dillen0https://archivedforum.beoworld.org:443/forums/thread/249648.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=30&PostID=249648<p>Welcome to Beoworld !</p> <p>Is there no reaction at all when you touch a source pad ?<br />- No click ?<br />- No flashing lamps ?</p> <p>Martin</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/249617.aspxFri, 01 Jan 2010 13:26:44 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:249617strangeadam0https://archivedforum.beoworld.org:443/forums/thread/249617.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=30&PostID=249617<p>i have a 2400-2 that does not start. the led is on and the power is working.&nbsp;I&nbsp;replaced the c92 cap and adjusted the15volt supply but no answer</p> <p>I have the solder&nbsp;, the screwdriver and passion</p> <p>Any help wellkome&nbsp;</p><div style="clear:both;"></div>
