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.

Site was easy to pick out my 45kva step up. Click, pay, 4 days later it was at my shop being wired up. Have a 480 press brake but only 240 so this was exactly what I needed.

Purchased transformer online. A representative contacted us promptly and handled any issues. Great to see there are still companies that care about their vendors. We will contact them again in the future.

Had a odd ball transformer no one had it but they did. Sent a truck from Jacksonville and they had it ready when I got there thank you.

John and Richard are absolutely fantastic to work with and will go above and beyond on communication, kindness and getting you taken care of. One of the best teams I’ve ever worked with.

I have been very happy with the three 15kva transformers we purchased from Maddox. The team is ready to please, friendly and actually helpful. The cost vs quality is unfounded. Shipping for these larger units was surprisingly fast too. We will definitely be doing business with them in the future!

Service was great, all was received in good order and quickly and the communication on status and shipping info was excellent as well. Would definitely use them again for any transformer needs and recommend them to others.

The people I dealt with were great! They were happy to make changes last minute on my order, when I messed up, and quickly remedied my concerns. Will definitely deal with them in the future
