Frying B2000?

    So I have had 2 Carvin B2000s spark out and die on me.
    Carvin has been very kind about replacements -- I'm not here to smear them.

    Inside the amp it looks like a part labelled "TR1" located near the power cord is what blew.
    So with this being the case it would seem like a problem with the electricity coming into the amp.

    I've heard conflicting opinions on talkbass about power conditioners but could one be a solution in this case? Or even just a good surge protector?

    Meanwhile most Furman conditioners seem to be labelled "1800W MAX" so would plugging a 2000W amp into one of these be a bad idea?

    2000 watt output rating is not 2000 watts power consumption, look for a VA value on the back of the amp near the power input.

    Unless there is a design flaw I would not assume power issues are what fried your amps.

    Has anyone else experienced their B2000 sparking out and dying?

    Power conditioners are in actuality a glorified, expensive power bar. Don’t waste your hard earned money!

    Give Carvin a call and discuss this issue with them. You could also ask them for a copy of the schematic. That device is part of the switching power supply. If you have had several failures that should be something that Carvin should address. None of my Class D/SMPS units have given me such a problem.
