    For more info here is the situation. I've got someone local offering an Ampeg SVT-6 Pro bass head for a stupid low price, they aren't a musician and have no music gear, and I don't have a speaker cabinet I can plug it into at the moment. I'd like to buy it, because who doesn't want a cheap SVT, but I want to test it somehow. Read the manual and don't see a headphone jack, nor any mention of them. I also know enough to know to NEVER plug headphones into the speaker output jack of a 1100 watt amp.

    Is there any safe quick way to test this thing without killing my ears, or phones?

    If you're in the U.S & near a Guitar Center, you could ask the seller to meet you there. Try it with the cabinets available there, be aware of the Impedance.
    If you're nice about it you'll buy the cabinet that sounds best with the amp.
  4. There's SVT's and SVT's, svt's and more than a few svt's.

    Dang, yeah "not really" was kind of what I was afraid of. For the price I might just buy it anyways because even having someone repair it would probably be worth it. Seller described it "all the lights turn on when I plug it in" so at least I know it's not totally dead.

    Guitar center thing is a good idea, but the guy doesn't live anywhere near one :( plus, got to think of the covids.

  6. Lights turning on is too far from a diagnostic for me. If you could find any cab at all it would be preferable to faith.

    Lights turning on means very little.

    Do you have any idea how much a repair could cost on that amp? I do, I can repair it myself, and I still wouldn't make that kind of a bet.

    Bring a cabinet along to test with, maybe borrow one from a friend?

    How much are we talking? they are asking $200.

    I don't know anyone local I could borrow from, might be worth just buying some on Craigslist or used at a music store really quick. Could always return or re-sell if the deal falls through.

    Thanks for all the help on this. If only the dang thing had a headphone jack.

    They sell for approx. $600 used.
    Worst case, you could easily spend more than the cost of a working used version on this unknown amp.
    I'll be the 4th; bring a cabinet.

    My main amp is a SVT 7 pro. Not really in love with it. It's just not warm sounding which is what Im looking for. Love the class D circuits and the lighter weight. My backup is an old 1000 watt solid state Hartke that sounds so much better but weighs a zillion tons.

    Long way of saying that you may be just as happy if you wait, save up, and buy what you love.

    Dude...sorry, but pass on it. You dont know if its working and dont have a cab to find out. It could cost more to have it fixed than its worth. Its not like its some super valuable rare amp.

    yeah I’m getting that impression. If I can find the means to test it I might nab it, but as it is from the awesome people on here, could be more effort and money than it’s worth.

    thanks to everyone who replied.

    Rent or borrow a cab from someone, and yes, get the proper impedance cab so you don't wreck the amp before you buy it. Don't forget to bring a speaker cable - not a guitar patch cord - to hook the cab up to the head.

    Even if it has a headphone jack that may not help you since it may be sourced pre power amp.

    Really, you could take a bath on this if it goes wrong.

    IMO the 7 pro and 6 pro sound very similar. The 6 pro weighs about a zillion pounds.

    I took this same risk on a similar style of head, and it had problems. I can’t sell it and it is so expensive to fix that I’d be better off buying another functional one used.

    Try it with a cabinet prior to purchase.

    The SVT 6 Pro is an EXCELLENT amp. I don't get too attached to gear. But one of my few regrets is selling my SVT 6.

    If you can possibly dig up even a monitor wedge speaker, go try it out (albeit at low volumes).

    If you're able to snag a working SVT 6 for $200 it'll be worth it. If it works and you don't love it, I'll pay you what you have in it (plus a little gas money) and pay you to ship it to my house immediately. You can't lose. If you do like it, keep it and rock the crap out of it.

    Again, any bass cab or full range PA cab will do for low volumes. (I wouldn't risk a guitar cab even at low volumes.)

    If you get it, PM me and I'll tell you a few things I learned about that head along the way.

    ok it's a solidstate head.. repairing it is going to be expensive.. sounds like if you pay $100.. look for it to cost $600-700 to fix..
