Went there to enquire about something sooo small and they helped me as if I was buying something huge. The thing that I needed was so small they ended up just giving it to me but they really went out of their way to help me and not once did I feel like they might have felt like I was wasting their time.

Eloff Transformers saved my business and my time. They repaired and tested my imported 5000w step-down transformer and went the extra mile sourcing additional parts with a smile. Their technicians are insightful, front desk friendly and management professional.

If you need your amp transformers rewound or new ones made, speak to Lilian or Zelda - they do a great job! Made a new transformer for me for my 1964 Showman which sounds wonderful now! They also have done many rewinds for me over the years. All at a great price and quickly!

I have purchased a custom wound power transformer for a tube amplifier and I must say, I am quite impressed. The Transformer is built EXACTLY to specification and has given me no problems whatsoever. This all came at a price I deemed more than reasonable for that specific kind of transformer. I would however like to see their website updated to give me a better idea of what their services entail, such as what transformer sizes they offer so that I can ask if they can make a transformer with that specific size in mind. Keep up the good quality guys!
