alright i have a GK 700 rb bi amp bass head. im jus curious, is the fan suppose to come on only when this thing gets hot or is it suppose to be on the whole time? Ive only seen the fan go on once and it wasnt even playing for that long, its never gone on since then.
http://www.gallien-krueger.com/PRODUCTS/HEADS/700RB/700rb.html It says... "Cooling:Continuously Variable Speed Fan" Continuous means all the time. var·i·a·ble [vérree b'l ] adjective 1. able to change: able or liable to change, especially suddenly and unpredictably So by thier description, it's always changing. I assume that means that it goes on when it's needed or it always on but @ different speed.
if its a "continuoues cooling fan" its supposed to be on all the time, and the hotter the amp gets the faster the fan goes to cool it down.
