Hi. The amp is a three year old Peavey Vypyr. The amp started smoking and the breaker in the power strip it was plugged into tripped shutting everything down. I've determined that there is a short inside the 3Amp IEC EMI filter. You cannot view this attachment.I've found a replacement online that I can order that has the exact same specs. I also found 1A, 6A and 10A rated filters with almost the same specs. The one spec that is different is the inductor spec. My questions are: Is the inductor used in that device what determines the device's AMP rating? And, would there be an advantage with using a replacement EMI filter with a higher (or lower?) AMP rating for this application? Thanks.You cannot view this attachment.You cannot view this attachment.You cannot view this attachment.You cannot view this attachment.You cannot view this attachment.
Assuming that there is a fuse somewhere on the amplifier, you will be all set to use a larger EMI filter. Just don't go smaller, or you will have the same thing happen again. I would go with the 6A myself.

Yes, there is a fuse. A t3.15al250v on the circuit board. And, in other news...

Looks like Ukraine shot it down ;D

Yeah, I'd say this is the issue lol.
These line filters live for many years.
Probably, the ac supply voltage exceeded more than the rating of some component for too long.
