AC transformer for 110V AV equipment
I took a chance and brought to Switzerland, some AV equipment that only works on 120V. I had, from a previous overseas stay in Britain, a 220V - 110V (3KV) transformer that at the time worked OK (the time frame was 2003). Now when the AV amplifier is working for about 1 or 2 hours, the circuit breaker in the apartment trips. I'm not sure what's going on here... OK the receiver is different - before I had a 110 watt / channel setup, now it's 135 watts / channel, but at the moment I'm only running R/L/C channels with a sub, and although the sub is not running from the output of the AV receiver is still on the same circuit. ...is the transformer heating up? is it just old? Could anyone suggest what is going wrong here? Anyone have a similar situation, who has been able to solve it? I love to have a nice AV setup where I live, and I don't want to spend 1000's again if I don't have to...
