 23rd December 2011, 04:50 PM #101 OlavHaal   diyAudio Member     Join Date: Oct 2010 Location: Haugesund Hi in these pre-christmas time! Hi all! Just to have a note before the holiday: my old schoolteaching tells me - if you have a halogen bulb with 24 volt and 100 watt = 24x24=576 divided on 100 = 5,76 ohm!! Then you have 3 in seriell= 17,28 with 300 watt. If you then keep 3 more in paralell to those first 3 you end up with 600 watt AND 8,64 ohm. That is pretty close - and if you give 1 resistor in seriell with those bulbs - you get even closer. I have found som small bulbs(halogen 100 watt, 24 volt) here in Norway. My SK82(KD33) was ordered 1 week ago. so the build will start in feb/mars! Happy New Year Greetings to all Olav
 23rd December 2011, 04:53 PM #102 Franz Gysi   diyAudio Member     Join Date: Oct 2007 Olav I was talking about 300W/120V bulbs, not 24V. O.K. maybe a way to go. Thanks for all answers up to now. Franz
 23rd December 2011, 05:01 PM #103 OlavHaal   diyAudio Member     Join Date: Oct 2010 Location: Haugesund Hi Franz Yeah - I know that it would be a closer fit with 300watt and 120 volt, but it is somewhat difficult to get hold on 120 volts bulbs here in Norway - and with 230 volt and low wattage bulbs it is even vorse(like 230 watt and 20 or 10 watt)! That is why I am thinking to try my amp with those 24/100 watt bulbs? Maybe? Best to all. Olav

Looks like a cigar

Yep.
