Why Choose Toroidal?

Most standard amplifiers use square EI transformers, but professional audio equipment is moving toward toroidal technology. Our units contain magnetic flux, preventing noise interference with sensitive audio circuits.

Custom Transformer FAQ

Can I order just one custom toroidal transformer?

Yes. Every custom transformer is wound to order, so single pieces are welcome. Need more than one? Mention the quantity in your request.

What details do I need to share for a custom transformer?

Your input voltage (usually 230V AC), the output voltage of each winding (center-tapped like 35-0-35 or single like 0-12V) and the current in amps for each winding. Not sure? Send a photo of your old transformer or its label on WhatsApp and we will work it out.

How quickly will I get a quote?

Submit the custom request form and we email you a quote within 24 hours.

What add-on options are available?

Electrostatic shielding, a resettable thermal cut-off fuse, high-temperature insulation (Class F/H), vacuum varnish impregnation and 5kV medical-grade isolation.
