Mesa Walkabout Factory Fan Fix?

Right on. I like a company that stands behind their gear.

 

I sent my head back to Mesa and they did the same thing for me. I also recommend the fan upgrade. I was blown away with their service.

 

ha ha ha....

 

Hi guys just purchased a red face walkabout, I doubt it is still under warranty. Was the bill 100 bucks for labor? I assume if out of warranty Mesa will cover parts but not labor?

Just want to clarify as I plan on gettin factory updates as soon as my WA arrives.

If anybody has time to list them it would be awesome.. i spent 30 to 60 minutes looking through the megathreads and just want to see if I am aware of them all.

Thanks

 

I just put a SilenX Ixtrema Pro Series (80mm x 25mm 14dBA fan 32cfm) in my Walkabout. Works great. It was $9.99

 

I hope you made sure that the CFM rating was the same or higher than the old fan.

 

From what I've read,the original pushes 36.5 cfm. The fan I bought is 32 cfm....My guess is it'll be ok.

 

I would not be happy with that change. You very well might run into overheating problems if you push the amp into a low impedance.

 

Yeah, my interactions with Mesa have all been positive...

Agreed - I would not have downgraded that fan just to save a few bucks and to make things quieter... I'm all about reliability and durability, and diminishing cooling air flow does not help either at all...

Unless you are flogging it below 4 Ohms or operating it in extreme heat you'll be fine. Happy thumpin'!

 

So how does these factory fixes work? You call Mesa's main number and ask them to update your walkabout?

 

I have no need to run below 4ohms anyways. I actually sent an email to Mesa to see what their thoughts are on it.

 

And.......

Don't keep us hangin' on a thread!

 

I just emailed them today.....when I get a response I'll be sure to post their answer.

 

I talked with Mesa about this very matter about two weeks ago and was told that there is no factory fix.

 

Well,I had practice tonight with the new fan in place. Running the gain at about 1 o'clock and the master around 10-11 o'clock pushing through a single 4 ohm /15 inch speaker I had no problems with heat at all. The amp was on for about 2 hours straight. It felt like it did with the stock fan. In between songs I had to make sure it was still working it was that quiet.

 

Here' the reply I received from Mesa about using a 32 cfm fan compared to the factory fan.

Greetings

Here is what our tech had to say:

I believe this will be OK, as long as there is plenty of ventilation around the head itself. I would remind him though that this will void the warranty if there does happen to be any issues.



Thanks

Hey fellas,
the fan mod involves putting a resistor in series with the fan.
This REDUCES fan speed and CFM. So the guy with the $9.99 fan wins.


Special double secret info: the series resistor also fixes a problem with excessive relay turn on time. Sometimes excessive = infinity. The voltage to the relay is rather low to start with (5 volt supply, 6 volt relay), and the current demand of the fan makes the situation worse, causing a 5 volt regulator to not put out like it should.
The series resistor fixes the problem just fine, and I assume the MB techs tested the amps with the reduced CFM at max power and saw no problems.
