Serious question - why does the Renegade need a fan?

[Resonant Alien]

I'm not asking as an attempt to indirectly complain about the fan - I'm really just curious...what is different about the Renegade versus other amps that requires it to have a fan??? Other tube amps, even other Eggies, run fine without one.

 

[Jeff Hilligan]

purely to get rid of heat. It extends the life of the tubes, boards and the amp. Especially with 34's!

Thanks Jeff. So theoretically it would run just fine without the fan - i.e. it's not going to blow up within a couple of hours if the fan wasn't there - it might just shorten to life span of the tubes, etc.?

I think fans are always a good idea on amps where the tubes are mounted upside down like the renegade. My Shiva had a fan like that too. Kept things cooler back there.

If the tubes are mounted rightside-up, you can just put a vent in the top of the amp.

Yeah, good point. hadn't thought about the physics of the upside down tubes

Yeah, since heat rises, the heat has only one place to go - directly upwards into the chassis and circuitboard.

I feel much safer that the fan is at least blowing some of that air out, instead of letting it go up.

Tourmaster combo is upside down and has a fan. Don't know about the head. I certainly wouldn't run it without the fan.

Now I have a design question - what is the design decision that drives some heads to have the chassis on top, and thus upside tubes, while some heads have chassis on bottom, and thus right side up tubes? Is it purely a cosmetic decision of where the designer wants the controls to end up - either on top or bottom??

Top mount allows for better access to the knobs than a bottom mount head. It just looks better and is easier to use we think!

Thanks.

Anyone know how to disconnect the fan? Nate told me you can disconnect it for recording purposes.

I think you have to pull the chassis. I saw no way to get to the leads with chassis in.

Will it not disconnect if you just reach in and unplug the two plastic connectors(the ones with one end coming from the mains and one end coming from the fan) ? I think there are some green markings on them and they just plug into one another.
