Smoked my B2000

Discussion in 'Amps and Cabs [BG]' started by PatentNonsense, May 10, 2015.

  1. My B2000 is less than two years old, and hasn't been gigged at all - so I was shocked to have it suddenly spew smoke and sparks when it hadn't even been playing.

    I opened it up, and the SL22 thermistor had blown. That's just a $1 component, but what would make it go out? The only thing I can think of is an external transient, and I didn't see any other signs of that.

    If that's all that's wrong it should be simple to get repaired - but is it?? I love the B2000's design, and was thinking about getting a second one, but this worrying.
  2. I'd contact Carvin and ask them.

    If you bought the amp with a premium credit card you might have an extra year tacked onto Carvin's one-year warranty.
  4. Geez I knew that!! Good one Bob! :D

    That feature has saved me $$$ on three occasions. Nearly instant full refunds (including tax) with a simple online application form--for a microwave oven, fancy toilet seat and a microphone, which all broke right before the extended warranty expired. The best part was the letter accompanying the refunds which thanked me and hoped I would use the feature again in the future! :thumbsup:

    Was it plugged in last night or this morning?

    The extreme weather in North Texas today caused a lot of power problems. Perhaps you had a lightening strike nearby? We did. At 6:43 am this morning, lighting hit a big tree in front of my neighbor's house. The tree came down and took out their power hook-up and the phone pole. We had might have had a surge and definitely a brief outage, but nothing seems toasted.

  7. Chances are very good the blown thermistor is symptom, not the cause.

    This is why - in spite of the inconvenience - I ALWAYS unplug my gear from the power source.
    I do that at home and when I leave my gig on a Fri night (to come back Sat night) I DISCONNECT power. I also take my vocal mic with me, but that another story..:)

    Never had ANY music gear fried while unattended.

    Had the same problem on a dcml power amp. It blew up once, failed another time. Not too confident in their reliability but they're nice in theory.
