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.

What is the output voltage of the mains transformer for the Onkyo SKW 770 Subwoofer amplifier? I need the specs so I can have a custom replacement toroidal transformer made. Thank you kindly in...


It would seem that a call or email to the mfr, should be your first move.
Are you certain that the transformer is at fault?
These normally outlive most everything else-

I get a humming sound when I plug my Gibson SG straight nto the amp. The noise fades and strengthens depending the positioning of the guitar in relation to the amp.


Your Gibson is sensitive to magnetic fields You need to keep the guitar about 10 feet away from the amp as the power transformer is radiating magnetic fields that is causing the hum. Solutions: there aree several... most are NOT practical... such as encasing the transformer of the amp in Mu-Metal shielding. Changing the transformer to a toroid type (they should deliver them that way) encase the amp in a thick steel cabinet... all this is ridiculous... putting distance between teh amp and the guitar is probably the only practical solution. The level given any particular orientation should fall off with the square of the distance. Note that OTHER stage equipment also will have transformers that radiate. Much of the new amps do NOT have power transformers that run at low frequency so they don't have this problem. Marshal is old school and they use the older power supply designs that radiate the magnetics.

How can i upgrade my av 302 to becomes best as konzert av-502


Hi,
upgrade your 302 to 502 need to replaced the toroid transformer, set of output amplifier, set of electrolytic capacitor.
Purchasing of these parts one-by-one is much expensive rather that you buy a brad new Konzert AV-502. Also upgrading the unit is quite tech and need a lot of experienced in electronics.
Hope that it may help you.
Have a nice day.

Hi, Toroidal transformer in Sakura AV-200T input is 220v I need 110v Thanks


Hello shole135, Hi, you need a 110v to 220v step-up transformer with 200 watts power specification. you can visit your local hardware store and find one. Don't replace the toroidal transformer.

Whining sound will not stop


The toroidal core transformer(s) is going bad. This will call for a unit replacement. Is it under warranty?

Nad 310 no power


The output should be 24v ac. Sounds like you have a busted transformer. Did you check out the resistor in front of the transformer.

You sound like you know what your talking about so I will not bore you with suff like glass fuses and thermal couples.

Good luck, I have had a few items like this over the years. Sometimes it's just best to send them in to the manufacture. I would look for a replacement transformer. 120v ac to 24v ac around 5 amps. Test it out and see if it works... If not, send it in.

I have a digitor subwoofer (A3111) and it looks like the fuse is blown. Looks like it needs a "F1AL 250V" fuse - but when I looked for one in the shops, I couldnt find it. Do they still exist?...


Firstly, the fuse is just a slow blow 1 Amp short style. You should be able to get an equivalent at any electronics parts supplier (a 1.25-1.5 Amp will do as long as it is the correct physical size).

Secondly, the cause of it blowing the mains fuse is probably a short in the primary winding of the Toroidal transformer. I have now replaced the transformer in mine twice over about 4 years.

If you cannot get the original Toroidal transformer (with the correct connectors) use a 50 or 80VA 12+12V Toroidal Transformer and connect the secondary windings in series. You should be able to get one for AU$30 to AU$40.
