That's the site. My thanks goes out to them all. Nice work on disecting all these speakers for us. cityjim

Sounds like it. Heard nothing but good praise from him and his work. Reasonable prices and fast turnaround times. cityjim

Sounds like U501 and or U502. Those are the N type MOSFETs on the AC/DC board. They are $2.88 each at Mouser.com. Then probably a couple resistors on the famous daughterboard, all on the same AC/DC board. Resistors are roughly 25 cents each. You'd need to check all caps, resistors and diodes on the AC/DC board. Go to the Thompdale.com site for all the schematics and drawings. cityjim

Probably blew the woofer. The 2.1 only has a 6.5 inch woofer. You trying to recreate a live KISS concert? cityjim

Don't have the schematic in front of me but aren't these speakers made for 120 volts? LIne filter filters the wall voltage/current. So you'd be talking about wall voltages. You shouldn't see 240 volts there. UNLESS there is some special 5.1 Ultras that can run on 240 volts. And if they are 120 volts then obviously plugging them into 240 volts might of caused the issue. You don't check those 0 ohm resistors with the continuity feature. Use the ohm setting. Should read like you touched both leads together. cityjim

Again like previously mentioned, possible BASH chip replacement required. Last I heard they're like $24.00 through Harmon Industires. Or a possible cold solder joint. Then there's the old standby ground loop. cityjim

Could of been a ground loop. Did you have your computer plugged in one powerstrip and maybe the speakers into another? Just a shot in the dark. Most likely the BASH chips or a simple cold solder joint. BASH chips are $24.00 last I heard. cityjim

Did you mention something about a church in the email? Don't want to get too personal here. And may I submit your contact info here for others to take advantage of? cityjim

Definitely an amp issue. You should NEVER have DC on the speaker leads. This is what blew the driver out of the speaker. 24 vdc caused the cone to fully extend and caused massive and continuous heat in the voice coil. Speakers don't last long with DC going to them. Your music signal is AC. Meaning a pulsating signal at a certain freq/s. Not a constant HELLO like DC provides. cityjim

Since you jacked the thread I'll add my 2 cents. I've read about several people that are not happy with Elliot and his service. However it seems to me the majority of people "eventually" got their speakers working again. Maybe it took too long for most kids to accept I don't know. Fact is Elliot doesn't snap his fingers and your amps is repaired. Most kids don't know the time involved in repairing these. Most are not a simple one resistor solder job. Elliot most likely has to order parts. That takes time. He probably has other things to do with his life and your amp is not high on his list. There are other places that do repairs. Stpetesheperd, heard good things from him. And this place http://www.sybesmas.com/home.html . And you sent him the amp. You had options if you'd do a little reading. Maybe you didn't know? You can post your experience with Elliot all you want. Just do it in your own new thread. You seem passionate about dogging out Elliot. If he deserves it then so be it. Again please start your own post about it. cityjim

The above link is dead. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=230476782396&ssPageName=ADME:B:FSEL:US:1123 cityjim

I clicked your link. Takes me to his ebay listing. Clicked on contact seller on the left. Takes me to the Ebay log in. Nothing about "this is not about an item" . cityjim

I'd repair it. Send it to Henry Koch or http://www.sybesmas.com/home.html . cityjim

It's an IRF740. Cost was $2.88 each. Got mine from Mouser.com . http://www.mouser.com/ProductDetail/Vishay-Siliconix/IRF740PBF/?qs=sGAEpiMZZMvECErq9cesgGC%2fTZBxItzsGj727qBiqJo%3d Also Thompdale has all the schematics and parts lists on his site. http://www.thompdale.com/bash_amplifier/5-1/5-1_bash_amp.htm .

Place it in the corner of the room on the floor. The 2.1 only has a 6.5 inch woofer. What do you expect a KISS concert from computer speakers? These don't shake the windows. cityjim
