Replacement Toroid Transformer

Hi All,

My Infinity SSW-210 sub just died and it turns out the toroid transformer died. I need to find a replacement but Harmon who took over Infinity will not help me. The Infinity part number is #499-5950 RevA which is a 130V Center tap. I can't even find it on the web when googling. Does anyone know where I can get one?

I know I need a new one as I can clearly measure 125v going into the transformer but nothing on the output at all. The output is supposed to provide both +65v and -65v.

    When I took off the thermal teflon tape to check the connections everything was ok and then I taped it back up and put some power through it and on the output I was getting both +65v and -65v DC and then after about 10 seconds it started making on and off buzzing sounds like something was arcing and then I turned it off as I could smell something getting hot/burning a little.

If you are refering to the DC +- 65 Volts the AC side will be different. What you need to find out is the average loaded AC volts on the secondary side of the transformer.

Below is the link to one of the biggest transformer companies in the world. I go to them all the time for transformers and power supplies for high end audio equipment and especialy for custom design and construction. I am sure they can wind you a new transformer once they know the exact specs you need.

If you do a Google search, there are a fair number of companies that do custom transformer winding.

Sub woofers have small amplifiers , not transformers. The amplifier is removable and replaceable. The The overall size and the output wattage are the spec's you need . The output wattage is on the label which is attached somewhere on the speaker. You do NOT need to replace the amp with the Altec Lansing brand. Have you contacted Altec Lansing to purchase a replacement Amp? That's where I would start. If they cannot help you I would Google replacement amp sub-woofer, Altec Lansing model MX5021.
good luck

You should look at the circuit board for the power amplifier and check for any leaking or bulged electrolytic capacitors. If this speaker uses the circuit boards made by AMI (such as most JBL and Mission sub woofers around 1999-2001 vintage) they had a lot of problems with this as well as bad modules. Google for the module S53AMI and you will find lots of info if this is what you have in that Athena.

Hercules XPS 210 sub problem. distorted sound


I think you've just answered your own question. It sounds as if you've coned the sub woofer. Meaning you've fractured the bond between the edge of the speaker body with the speaker cone. Or overheated the voice coil and it's distorted and not getting free movement. Excuse the Pun but it "sounds" like you need a new speaker as a replacement. If it's a particularly expensive speaker it can be reconed. A check of the Net for someone close to you will find a company who recones them. If it's a cheaper one then a replacement would be in order.

When i turn my infinity servo subwoofer ssw 10 on and it just blows the fuse


Then it has developed an electrical fault and will need to be repaired by a technician. Sorry to bring you bad news.
Do you mean the house fuse, or the fuse built into the back of it?
If it is the fuse in the back of it, are you definitely replacing it with the same rated fuse?

Repair or replace?


If the rip or split extends from the voice coil out to the edge, the speaker may be too far gone to replace. I have repaired expensive speaker cones with epoxy cement, provided the tear is fairly small or narrow. No noticeable degradation of performance either.
