anyone know where i can purchase a bunch of transformers for a good deal? im looking for 120v primary 24volt secondary at 2 to 3 amps. i need about twenty or more. or a good deal on more amperage and i can share the voltage. i need to make a bunch of audio amplifiers
Are trying to get +/- 32 volts? There are many ways to do this.
The goldmine transformers don't look to me like the wire is too thin; unlike some transformers the wires are solid not stranded, and the insulation is thin.
A single 24V-0-24V transformer is likely to be much cheaper than two 24V transformers. You could also consider a transformer with two 24V secondaries or just buy a pre-built switching power supply.
im building audio amplifiers and need a positve and negative voltage. i can't find any good deals on 48 volt center tapped transformers. it looks like i can get the 24 volts at a good price though. a premade switcher would be nice but that would probably be the most expensive alternative.
