Tube amp being vertical - bad?

    Hi all

    I did a search but all it comes up with is stuff about upright basses (dbl bass). I have a svt cl with a road case that has wheels on one end and a extendable handle (like luggage/suitcase). A couple of times I have left it standing vertical. My question is, is it bad for tube amps to be vertical/on their ends like that? Can it do any damage to the tubes or other components or is it fine?
    Appreciate any advice. Thanks

    I can't think of any reason that would be a bad idea, except it being a bit unstable. Just don't let it fall over.

    Stability is no issue it sits fine. Found a picture of a case the same. Didn't think it would be an issue but I've never owned a full tube amp before so wasn't sure.

    No issues at all doing that as far as the amp is concerned. I keep my SVT in an ATA case on its side because it takes up less space.

    The only potential problem is not with the amp but with the ATA case. On its side, there is more weight spread over a smaller surface area. The end of the amp is smaller than the bottom. Depending on the type of foam that you have in your case, it might compress the foam more and with time, this compression might become permanent. Not a big issue and a lot of "mights". Descent cases have good quality foam that this wouldn't be an issue with.

    Some valves/tubes can only be used orientated in certain ways but none of them end up in valve/tube amps.
     
  6. I'd not do this as the cooling flow for the amp was designed for the amp horizontal. If the amp has a fan it's probably OK but i'd still use it horizontal.

    Moving them vertical is fine. Running them vertical will cause uneven heat distribution across the tubes vs being run horizontally.

    Making the electrons going through the tubes while sitting tilted 90 degrees will cause the sound to come out out of phase. You can use a phase shifter pedal to correct the problem.

    The CL fan runs constantly, or at least it should.
     
  10. Wrong thread! ;)

    If you're in the wrong thread, go to a different one.

    Downside I can see is cooling as the tubes would be in a vertical row and the heat from the bottom ones will rise into the top ones. I don't know if the amps exhaust fan is enough to combat this but an additional small fan in the rear blowing on the power tubes should help take care of it.

    Then of course there's Fenders where there is no cooling fan and the tube heat rises right up into the amp and they last decades, so.....

    The advantage of the pedal is that you can adjust the phase for any angle. This is opposed to a phase aligned speaker which fixes the amount of phase correction.

    But it doesn't work for metal. Head bangers are constantly changing the phase that they perceive when they bounce their heads.
     
  14. No problem being vertical. My SVT has been sitting vertically in my office for the past year. The only problem is it hasn't been getting used for the past year.

    I don't do it. It just seems wrong. I don't like to even pick an amp up or set down vertically as there is going to be some lateral pressure on the sockets. Once or twice, no big deal...but as a regular practice I wouldn't do it.

    So what you are saying is there is no best phase for metal?

    It depends on the song. That's the problem with metal, it's way too technical.
     
  18. The cooling/heat build-up issue is what came to my mind right away, too. Something that could probably be dealt with though, even if just run a small fan blowing on the amp.

    Why don't you just contact Ampeg tech support?

    Actually, I'm interested in this for my EBS head. If I can get away with standing it on end, I could stick my SVT 210AV on top and not need an amp stand :)
