    Storing a tube amp Advice please.

    Post by Ernstmach on Sun Mar 26, 2017 11:17 am

    I have an amp that I will be storing, likely long term (years).
    Any advice that will help to keep this amp viable when pulled from storage? Is that even possible?
    It will be stored in a sealed plastic container with desiccant pack.

    Thanks!
    Bob.

    I would imagine you should remove the tubes, though I'm sure you've already planned to that. In order to minimize corrosion perhaps placing the amp in a heavy duty vacuum bag with desiccant and then removing as much air as possible.

    Or you can send it to me and I'll take care of for you. :-)

    Store in a climate controlled space without large swings of temperature and humidity. Electolytic capacitors would probably be biggest possible issue in years to come. Heat can also degrade wiring insulation. So keep it out of the attic or garage.

    Keep it dry, in a conditioned space if possible, and away from any form of dampness. I suggest double-bagging it with a desiccant. Keep the tubes wrapped separately and protected, in the same bag.

    Remember that the biggest issue for re-start will be any electrolytic caps.

    No problem. Enclose any documentation you have, leave tubes in place,
    store upright in case some cap leaks.

    Just put it in the barn, packed tight with acorns, leaves, bugs, and dead mice ...

    (oh, the horrors I've seen)

    Anybody ever try one of those vacuum bags you hook up to a shop vac? Couple desiccant bags inside, and it should be pretty much bulletproof storage. Your electronics will still degrade with time, but without mother nature's help ...

    If it's got a cover, I'd go ahead and leave the tubes in place. If nothing else, it'll make it easier to withstand the urge to knock the thing around in storage.

    Thanks for they advice everyone.
    I just ordered a 20lb's of acorns and interviewing mice for the job sKiZo! Laughing

    Would leaving the tubes in be a good idea? I'd rather pull the tubes. Should the pin sockets be treated with something?

    I'm thinking a large ziplock type bag and purging as much air from it is maybe the way to go.
    This will be stored in a closet that would see no large fluctuations in temp and little chance of being bumped.

    This is a pretty good amp, not as good as my MKIII's. I have tried selling it but can't get what it's worth and shipping 60lbs scares most buyers off so I'll let my heirs deal with it.

    Thanks much!

    one very good reason to let the tubes remain in their sockets is to save
    the tubes from destruction. They are better protected there then in most other environments, and they don't have the stress associated with tube removal. Nor
    do they risk malplacing when in the future the amp is started again.
    Make sure no bugs may enter, a vacuum-sealed bag as suggested might be a
    good thing.

    What make/model amp is it?

    If you are going to vacuum bag it, I would recommend wrapping it in some kind of cloth and then vacuuming it. I've done this with a lot of things and simply vacuum bagging usually results in the vacuum cutting the bag on a sharp metal edge. I would recommend a secondary seal and dessicant also. Storing it in an air conditioned space is ideal. I would build a wood box out of scrap ply wood or something if it was going to be left somewhere where a friend might have to move it and possibly damage it. See my other comment about blowing a cheap solid state amp? That was done by a roommate of my buddy (never could prove it) who hooked it up and used it when I had gone home one summer. I had stored my stuff with him. His roommate wasn't the best......

    I once had a few pros that would love that work. We have cats now in all locations that use tubes, so those pros have been dispatched to a better place.

    Would leaving the tubes in be a good idea? I'd rather pull the tubes. Should the pin sockets be treated with something?

    No and no. No-1: Because if any corrosion does take place, the tube pins may 'weld' to the sockets. No-2: Because any treatment may not  'stop' and continue to eat away at the sockets should they be anti-oxidants.

    I'm thinking a large ziplock type bag and purging as much air from it is maybe the way to go.

    Yes. Add desiccant packs to the bag, and use two bags, each with its own desiccant. Remember that Zip-Lock bags are not often entirely air-tight if not very carefully sealed. So, check about a week later to make sure that the seal 'took'.

    This is a pretty good amp, not as good as my MKIII's. I have tried selling it but can't get what it's worth and shipping 60lbs scares most buyers off so I'll let my heirs deal with it.

    Thanks much!

    Ernstmach,
    Since the amp(s) are going to be your heirs' problem, just dip the whole smash in Cosmoline. It can be removed 50 years later with low heat or with mineral spirits, *meaning paint thinner, not gasoline*. Won't save your electrolytics but it will keep everything nice and dry.

    Cosmoline certainly will protect the amp from corrosion as long as it doesn't crack. When I worked for Boeing Helicopters tooling and gages were dipped in Cosmoline after use to protect them from corrosion. But none of the fixtures included electronics. Cosmoline would turn everything into a mess.

    Wrap the amp in a soft cloth after removing the tubes. Wrap the tubes individually in soft cloths also. Then put everything in a vacuum bag along with desiccant. And suck as much air out of the bags. Store the amp in tubes in a sturdy box that won't collapse.

    "just dip the whole smash in Cosmoline"
    Now there's an idea! I could then bequeath it to a family member I like the least.......


    "Cosmoline would turn everything into a mess."
    Yea, I have dealt with it a bit. Cleaning up some Army surplus items.

    I'm thinking of lowering the price to move it on. Or give it to a budding audio enthusiast that could learn to appreciate what the hobby has to offer.
    Thanks for the thoughts everyone!

    IIRC, you never said what kind of amp it is, what you want for it, or where you've got it now.
    Yeah, the Cosmoline was a joke. Getting that stuff out of a mothballed pistol or rifle rivals continuous KP.

    I disagree with leaving tubes in an amplifier that is being put in storage. I always save boxes of everything I have concerning electronics, even tubes boxes.
    However, one can always invest in a little eggcrate foam to store your tubes for a lengthy time period.
    As for the amplifier itself the idea of storing IT in a vacuum sealed bag is an excellent idea and safe from the elements for years.
    You might consider the same process for the tubes after you wrap them up in the aforementioned egg rate foam.

    Problem solved. Managed to sell the amp.

    From storing to selling.
    Well I guess you can always buy another one when you are ready.

    Out of curiosity what kind of tube amp did you decide to sell rather than store?
