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.

“I spoke with Josh Long and he was the most knowledgeable sales rep on transformers I had the pleasure of speaking with during my 2 month long ordeal to find a very specific transformer for my machine from overseas. I really appreciate his expertise on the matter and I look forward to working Josh again.”

We had a customer who lost their primary transformer in the middle of the night. Maddox was able to get a temporary transformer on site in hours. They also rebuilt the damaged transformer in record time while no sacrificing any quality. I would recommend Maddox to anyone for transformer needs.

“Was in a rush and needed a transformer and called these guys...best thing I ever did! They were super helpful and actually had a transformer I wanted but didn't think I could afford. I had it within 3 days!!! The transformer works great and the folks were very nice and knowledgeable about what I needed. They didn't try and upsell me or anything like that. THANKS!!!!”
