Hey guys, can anyone suggest a toroidal core for ac mains?(60hz) I am ordering an IC power amp and it takes in AC mains for the supply rails and I want to wind a 1:1 center tap transformer so I can simple keep the voltage the same but split the voltage in half for a dual voltage supply for the amp.

Actually you are probly right, anyone know an already made transformer for mains that hardly steps the voltage down(100v secondary is fine) or 1:1? with center tap..

Unless there is a simple solution to create a balanced split supply but i know that it is very difficult to keep them balanced.

55 dollar is indeed a very good price.

I have such a toroid here. Shorting them is not adviseable at all- they will start to fizzle immediately and turn hot within seconds.

Rectifier diodes will explode immediately as well.

I use a bridge with a large heatsink. Right now only one winding at 200 Watts.

Unfortunately, Antek Inc. recently suffered a fire in their office and warehouse spaces. Try to be patient, as it's going to take a little time to re-build and then build up their inventory again.
