drop KD an email telling them whats up, if they send you a new driver, desolder the center spring, desolder the driver from the brass pill, desolder the two wires from the emmiter after removing the plastic ring covering it and resold to the new driver wires then fill the gap between the driver and brass pill with thermal past (optional) and resolder the driver to the brass pill then resolder the sping the the center, make sure all solder jonts are true and correct you dont want any cold solder joints, it is hard to solder the driver to the brass pill and the pill takes a bit to heat up but the driver does not and check all joins you make and that where on the driver, i used a 35 watt and 70 watt soldering iron to mend my kd c8 and settled for 1.5 amp on crap batteries the draw is less on good trustfireflames.
this is the driver that is in mine and KD sent me this driver as a replacment, but KD tell me the kd c8 is direct drive..... i have not bothered with it.
if kd dont send you a new driver you might have to buy one if you realy want to fix the buzzing, you have a 1 in 5 chance
if you where in australia i would send you my spare kd c8 driver, if you do want to go ahead and replace the driver you will need some basic tools
solder
flux paste
thermal paste (optional)
an adjustable wattage soldering iron (i used two soldering irons (35 watt fine tip and 70 watt flat tip) as the brass pill can take some heat to get the solder to run)
a digital multi meter to test the new drivers you dont what to put in a dud one.
and i use a soldering multi tool it has 4 arms on it with clips, it will help with holding the battery spring in place and the driver in place when soldering it realy helps.
? magifing glass to check factory joints on the driver can help as my eye are not as good as they once where
if you dont have these items (i did already) it might cost to much or be to much trouble to replace the driver so keep using it till it stops or look into a better torch.
I think I'll let it buzz and hope for the best. If it's dead silent, i can hear it up to 50cm so when using it in a normal fashion it shouldn't bother me i hope.
Hello. I have a few questions. Does anyone know if the 3-mode KD C8 will have the same ~3amp draw as the 5-mode? Are there any decent holsters around for the C8, or at least one that will work? I'm diggin The 3 mode. I hate sos, but strobe has been useful to me for more than one reason. Does anyone know how low the low is on the 3-mode? I hope it's spaced out well. 100 lumens sounds great. Maybe even lower. I know that's a high hope though.
I spent 45 minutes with my dremel tool and some polish. Now my light looks as good as it performs! Two weeks ago I went motorcycle camping with about 15 folks and there was no electricity . everybody had flashlights and some had expensive surefire lights. My buddy Geoff has over 150 dollars into his . This light not only blew them all away, but it was brighter than some of the motorcycle headlights. As folks were setting up their tents they would leave their headlight on to see why they set up. I would come over with this light and it was brighter than some of the headlights.. pretty impressesd so far.
My gf tried this on her bike as bikelight. She drives to her workplace in the morning when it's still very dark here. Oncoming car's were flashing their lights when passing by, so this is powerful, perhaps too powerful for bikelight. I think she will continue using SSC P7. But this test had to be made, right? :)
