    Hey everyone. I purchased a Henry 2K Classic Amp a few months ago and absolutely love it. It's integrated nicely with my TS-830 and has opened up a whole new level of enjoyment in the hobby for me.

    I do have a question though, exactly how "loud" should it be? Almost all the reviews I've read say it's loud, but in all honesty I can barely hear it. If I put my hand to the side of the amp when it's on, I can feel a vibration so I know the blower is working but I have no idea how much air is supposed to be coming out of it or how loud it's supposed to be. Is there a test I can run or should I shoot and post some video?

    Thanks,

    Don't shoot.

    I would measure the temperature. That's the important thing.

    Id suggest cleaning and lubricating the blower and then have a reference point.

    The 2K series weren't very "loud." It's only a pair of 3-500Zs and the blower isn't all that big. They can make "rattling" noise if the cover isn't sitting completely flat, or if something's loose.

    If it is a pedestal model amp, which it should be, check to make sure the filter is clean.

    This guy was called "Quiet Henry," but I think that was before amplifiers.

    Hi Kevin,
    I have a Henry 2KD Classic it is not very loud at all. But like Steve said to lube the blower at it lube points on the blower. I do mine here about every 3 to 4 years. Use some 10 weight motor oil.
    DO NOT use 3in1 if you want to keep the blower. I have a spare amp that I use for parts if I need it. Also WW Grainger sell a replacement blower for the amp. Good Luck.

    There is a special oil for fan motors, as said. If you have an HVAC supply house, they will have it. It also has a long flex tube that comes out to fit in weird places.
