Need a fuse for PSW140

I have a PSW140 that needs a new fuse - AGAIN :-(

I was told by someone at Polk last time to get a 1.25 amp, 250v 1/4" X 1 1/4" fuse. I got a box like that from Radio Shak, only they're 1.5 amp instead of 1.25.

My problem is every time I put a new fuse in and plug in the subwoofer, it immediately blows. I unplugged the speaker to see if that could somehow be the problem, but a new fuse still blew immediately. I even unplugged the subwoofer from the receiver, so that there was nothing but the amp and the power cord, and the fuses still blew immediately!

Am I using the correct fuse? If so, what could cause it immediately blow like that? It's not the receiver and it's not the speaker. Either I have the wrong fuse or my amp is messed up.

Please help!!

Thanks,

Mike

    Hi Mike:

    From what you say about your trouble, I believe your amp has a problem.

    Hello Mike,
    The AC fuse in the PSW140 is a 1.25 Ampere 250 Volt standard 1/4" by 1 1/4" time delayed fuse. However, having the fuse continue to blow is a result of a problem in the amplifier. It would be best to remove the amplifier and send it to Polk Audio, 2550 Britannia Blvd., Suite D, San Diego, CA. 92154. Please include a short note giving us your name and address and a daytime telephone number and a copy of your sales receipt. The service department will determine the best course of action, usually within one or two days of receipt.
    I hope this is helpful information.
    Regards, Ken Swauger

    Hey Ken,

    Thanks for the advice. I have just finished packing up the amp and am sending it back to Polk Audio like you suggested.

    I bought this subwoofer in January of 2000 and this is the second time this exact problem has happened to me. I sent the amp back about a year and they sent me another one, free of charge, which had been working fine up until now.

    I have the subwoofer on a surge protector. Do I just have bad luck, or is there something I could be doing that could cause this?

    Thanks,

    Mike

    Hello Mike,
    Sending it to us is the best thing to do. The only thing I can think of is to make sure your surge protector is adequately grounded. These devices shunt any spikes in the incoming AC Voltage to ground, operating in billionths of a second. But it is important that you provide a good ground through the protector's AC power cord. There are AC outlet testing devices found at most good quality hardware stores. You plug them into the wall outlet and a series of green/red lights indicate the validity of the outlet's operation. If you live in an area where "brown-outs" and frequent electrical storms happen, this could be helpful.
    We'll handle your replacement amp as quickly as we can.
    Take care, Ken
