Hi all, I have a Gallien Krueger 700RB 1-15/tweeter combo with a fan in the top that does not seem to be working. I checked resistance on the fan (about 1.9 meg) I am not sure where its supposed to read, I also hooked it up to my bench DC supply and set it for 20 vdc, its a 24vdc brushless fan and does not work with my DC supply so I figure its dead anyway and I checked the connector on the pcb where the fan coonects, there is not volatage at the pins on the PCB either. Does it only come on under exreme demand? Please let me know what you think, we need it for a gig this weekend. Does anyone have a schematic on this that I can look at? The bass player says the sound was cutting out the other day in the heat and the fan did not come on at all obviously... It looks like a computer power supply fan.
Thank you
