Having the largest transformer inventory in the USA doesn’t help anyone without the team behind it. At Maddox we pick up the phone when you call and ensure you get the transformer you need when you need it.

Company rep very knowledgeable, friendly and proactive in helping me with my needs. Providing help each step of the way in my search for the right transformer. Inventory was good. Highly recommend.

Couldn't ask for better! From sales to shipping, to accounting. Item arrived as specified, expertly packaged for shipping, email notifications from all for tracking, billing, and assurance of delivery. It is so gratifying to know there are still companies and these kinds of people in the USA to deal with! Refreshing in these times.

This was my first purchase with this company. It was an easy experience purchasing the item I needed online. They offer a very competitive price, and the delivery was as promised. Look forward to doing more business with them in the future.
