I'm bringing out my SWR SM-400S amp after a few months and had a couple of questions: * Once the fan comes on, it stays on for quite awhile. I just finished playing the amp until the fan switched on (bridge mode into 8 ohm Goliath II cab). It took 11 minutes...no playing during that time...until the fan went off. The amp is in a rack and it has one full open space above the amp. Is this usual? I'm wondering in part because the fan sensor went bad last fall and I had it replaced...want to be sure it's working right. * The amp requires quite a bit of gain before the clip light starts to flash. With moderate EQ and enhancer at 1 o'clock, I need to turn up the gain to about 3 o'clock with my Jazz bass pickups full on before the light flashes at my usual playing level. Is this where you're setting the gain for passive instruments? Thanks for your ideas...it's a nice amp, but these two things seemed a bit unusual.
