    I have had my GK for a few years. It seems, per the repair shop, that the fan has gone bad on my 700rb. Fans are usually warranted by MTBF (mean time before failure) at minimum should 20,000 hours. I know I have not used my amp for 20k hours. Amp is outside warranty but fan may still be within MTBF from the fan manufacturer. Who's fan do you use and what is the MTBF of the fan ?

    A new fan for your amp will cost about $20. Are you really going to pursue this? Isn't your time worth more to you than that????

    MTBF is not a warranty at least that I have ever encountered in consumer or industrial electronics. It is "expected" service life that is usually also tied to "continuous" use or "power cycles".

    If you think you will find anything different you might be in for a surprize, enjoy the journey? Expect disappointment. The last "lifetime" warranty I know of was Acoustic Control Corp. and they went out of business back in the 1980's.

    You have received a "service response" from whom, where?

    By the way I have way too many hard drive failures taking with them important (to the user) data at well under 50% of the expected service life MTBF. If the drive was outside the number of years/months warranty the drive manufacturer specifies guess what, your out of luck. No working drive and no data.

    I think the GK warranty is two years; and, when I've needed help from them, they've been really helpful.
    If you haven't contacted GK customer service, you should. They might help you; but, they sure can't if you don't ask.

    I have sure never heard of any amp manufacture extending warranty on a cooling fan in terms of MTBF......

    If it were me, I'd install the GK $20 replacement fan, and get on down the road; especially if it's an amp that you otherwise really enjoy.

    What do you have to lose there, OP? I'd say getting the part and replacing it would be far less hassle in the long run.

    Yep, too bad the service center charges 90.00 an hour to replace a fan. Please pay attention to the issue, not blame and finger pointing.... Just use a fan that last longer !

    Every single part in every single piece of equipment you own has a random chance at early death. Count your lucky stars its a small cheap part. Quit complaining about the cost of skilled labor if you can't do it yourself. If you can, just do it and quit complaining about the life of a fan.

    Color me optimistic, but I can't imagine a fan replacement being THAT hard...I'd imagine some unscrewing and some wire-to-wire soldering would be all it takes.

    I've owned six different GK amps in the last seven years. Four of them went through several years of heavy rehearsal and gig use, and only two of them were purchased new. Two of the previously owned amps were 700RB-IIs. Only one of my GK amps ever failed, and that was the result of someone else accidentally frying my Fusion 550 in the weirdest and dumbest of ways. The rest of my GK amps, I sold for various unrelated reasons (namely, to fund a GK Fusion 550 purchase, and later, a GK MB Fusion purchase), and although all of them had seen plenty of gig action, you'd be hard-pressed to tell.

    I still own and use a GK amp as my primary amp because of how reliable they've been for me. Oh, and tone, too. :D

    Even the most stringent testing standards cannot prevent the occasional premature failure of a part. If this was a more common occurrence among 700RB owners, I'd be concerned. As far as I've seen, it's not.

    Well you are making quite a splash on your first post here? (Join date TODAY)
    Might I suggest sourcing your own if you have no faith in it being the odd occurrence.

    www.mouser.com www.digikey.com are good places to start your search. Here are some pertinent specs for the fan:
    FAN, 24VDC, 160MA, 80X80MM

    I feel like it cost me $20 worth of time just to read this thread.

    Buy a fan and replace it. You should be able to do it yourself. It's not that difficult.

    It's not that big of a deal to start, and the expectation that you'll receive any sort of free service is naïve. Electronic components fail- eventually, all of them will. Count yourself lucky it's a cheap fix and move on.

    +1 on GK service. They answered the phone in English, were actual techs, and were wonderful to deal with, IMO.

    The fan plugs in. Unplug the amp, get a screwdriver and replace it. It shouldn't be a difficult job.

    Did you think that your fan is the odd one and cacked before its usual life span? Blasting a manufacturer for the failure of a part they didn't make is BS. In life, it's necessary to pick your battles. This one isn't worth getting your shorts all bunched up.
