    Or corroded input jacks. Sounds like some Deoxit treatment is in order. You never know how long this has been sitting in a warehouse somewhere. My guess is it’s not anything serious.

    Ya, good move. You definitely need the back panel off to get the pre in. Saves way more time to do that than to try to get it in without doing it.

    Yeah spray some stuff in it and void the warranty... that's the last thing a tech wants to see.

    I'm just happy to have it back working. I didn't have very many hours on it before it started messing up. It's very discouraging to spend that much money on something and have it fail.

    I hardly ever buy new, but i figured i should do so in this case because of a warranty and all. I live in a small town and amp techs are hours away. The idea of having to ship that beast was not something i was looking forward to.

    I really didn't think it was the tubes because of the crazy sound it was making.
    I didn't know bad tubes could do that. It was down right frighting lol. I own three other tube amps and have had them for a long time and have never experienced something like that before.

    Also i am excited to see what Yamaha brings to the table. They make good stuff and have plenty of money. I'm hopeful that Ampeg has a bright future ahead of it.

    I have. I thought it could be the problem. I always suspect a tube in situations like yours first thing, and I usually say so, but occasionally I get jeered for being irresponsible and cavalier with my over-the-net layman's diagnoses because it could be something else and I'm "encouraging people to spend good money after bad." Meanwhile, I could have been a hero instead of an also-ran.

    :D

    I agree, Al.

    And, because it's a Heritage model, my gut feeling is that it won't be hard for Sweetwater to get the replacement parts, if they don't already have them on hand.

    Been using it for years. Zero issues. Hasn’t effected any warranty repairs either.

    It's a tube amp! It needs regular maintenance. Tubes are on sockets for a reason.
    High voltage, loose connections, it happens.

    Doing what's right, being responsible, self improvement and the like can only lead to one thing. Higher expectations. Who needs THAT!?!?

    You have been lucky.

    For others here, don't do it!

    I would extend that and say that all amps need regular maintenance.

    Ideally, look at maintenance as an inspection with tasks performed, and a certification provided that the amp is performing to spec.

    Tubes do require some extra attention but in general they have a long service life.

    Depending on the procedures covered, what you get out of it will vary. With some rare exceptions, comprehensive service manuals don’t exist in the musical instrument industry anymore. Professional audio equipment tends to be the exception.

    I don't wait 30 minutes after eating, to go swimming.
    Why, the chair part is made of wood but the naughty bits (that conduct that pesky 'lectricity) to the human(?) body are of course, of metallic composition. If the chair was all metal, a whole set of problems would arise, such as probably making the "event" more of a barbecue ;)

    Sure - and the first thing to check on any gear is the consumables.
    You can tell what the consumables are because they get written as exclusions in the factory warranties ;)

    That’s true. Check tubes and sockets first when problem solving. Some speaker cabinets also have shorter warranties than the amps that they are paired with.

    Modern day consumables include the computers that we all use. I like to upgrade around every four years to ensure that these tools can cope with acceptable performance specs and offer up to date features. I have tubes that last longer than that. Unfortunately, that applies to a lot of consummer electronics. Yet we still use them.

    Are you aware of who agedhorse is? Unless you have more experience with amps than he, I’d take his advice.
