    I'm very new to tube amps and understanding them. I recently bought a Traynor Bass Master 40watt. Very cool and different type of musical experience under the fingers. I played a gig the other day with it and it was fun! But by the end of the evening I could hear some break up. 3 hour gig and it was on for all 3 hours.
    What volume setting do you bass player get at when you notice breakup? I don't know if its been modded or not. I would like to hear what other people may think before sharing my volume knob level that night.
    Thanks peeps

    Pushed and on for that long you are gonna get some break up, most folks using that amp desire that, in guitar circles that one, is prized as the Canadian Marshall alternative. I would love to get my hands on one.

    You don’t mention which input you are using, and ganging the two channels changes everything. With the hotter input on the bass channel, depending on how hot the source is, I’ve had YBA-1’s stay pretty clean up to 5, and some start breaking up at 3.
    Typically for my setup, clean up to 3, more distortion and more volume from 3 to about 6, from 6-10 it just gets more distorted and compressed, but not really louder. It’s plenty loud by 3 or 4.

    I love the sound of a stock YBA-1 into a single EVM 15L. That’s my youth.

    Each amp is different, and it depends on how hard you are digging in, the health of the power supply caps, the tone settings, how hard the speakers are being driven, even the tubes own distortion characteristics.

    With the tone controls set flat, you can turn up the volume to a point where distortion begins to be heard. The more the bass tone control is dialed up, the sooner the onset of distortion. With the bass tone control turned up, you will have to turn down the volume to get back into clean sound. They balance each other in that respect.

    Note that distortion occurs over varying degrees, from mild compression to full fledged nasty dirt.

    Breakup and distortion are two different things. Some folks use either to describe dirt. Breakup usually refers to speaker distortion.

    With a 40W tube amp it’s more a matter of trying, vainly, to get a clean bass sound. :(

    Yeah its low wattage
    And EL34 pentodes
    If you get past half way up and it's clean I'd be surprised.

    My first tube amp. Loved it.
    Used pair of matching 2x15s
    Sealed with factory Tranyor drivers.

    Mine had slightly less breakup after I replaced the rectifier and caps. It started blowing fuses.
    When I say less it was very very very little less. But it had nice feel to it after the caps

    Don't let it fool yah it's enough to toast some cabs. I later bought some old beat up Ampeg V4B 412 guitar cabs. Just one almost carried the room as good as the 4x15.

    Loud enough for sure. But never clean for loud drummer. For lower volume blues or light jamming. It was cleaner and sounded good. It still toasted most the V4B drivers. I'm sure they were already abused before I got them

    Real trick is to run alot of speakers. And wire them to work with the limited output tap

    I'm looking for an audio clip ... know EXACTLY what you're talking about, but looking for a sample to share with the not-initiated
