What Our Customers Say

I’ve been using E&I power amplifiers in my research for over 20 years, and I couldn’t be happier. Not only are their products reliable and truly world-class, but working with Jeff and his team has been an absolute pleasure. Their customer support goes above and beyond.

We have been using E&I amplifiers for > 10 years in our human LIFU studies, and their exceptional quality and durability have been outstanding. The amplifiers are robust and reliable, performing consistently with no issues. When we have needed support, Jeff Keller and his team has been incredibly helpful, providing prompt and knowledgeable assistance that ensures our work continues without interruption. E&I’s commitment to excellence and customer support has made them an invaluable partner in our research.

Just a note to thank you for all your help given to our electronics Technician, which enabled him to repair our amplifier. The swift dispatch of a replacement board was very welcome.

The E&I 1040L has been successfully received and we are eagerly awaiting the E&I A300. Thank you for the amazingly fast delivery time.

Asked for a service manual for our old ENI amplifier. Received reply within hours. Documentation received was high quality. First class service. Amplifier back in service. Result!

Your web site says "We offer unparalleled service and support" and it's absolutely right!! Thank you so much for getting back quickly and resolving my 320L problems.

We have used ENI amplifiers in our EMC lab for 15 years. They have proven themselves to be very robust and reliable. When E&I was formed and would provide service for our existing ENI amplifiers I was very glad. Finding a repair house for older equipment that performs well is not usually and option. I recently sent in my 6100L for repair. Even though E&I does not manufacture a new version of this amplifier, they were able to repair it in a cost effect and timely manner. Thanks to your team at E&I for helping us maintain an important asset at Intertek!

Just wanted to let you know that we are very pleased with the E&I 325LA that we recently purchased. Most impressive for us is the conservative specs. This amp comfortably delivers 50 watts when needed. We had a particular application at 210 MHz; no problem. Harmonic content is lower than other amps we have tested, always nice to see. Compact, lightweight, great for our lab. We have recommended the 325LA to our production facility.

I would like to extend our sincere appreciation for the excellent technical support, service and integrity that E&I provides. In 2008 we purchased a 2KW RF amplifier from E&I and found that we needed more power than the specified maximum. E&I was there to help us and modified the unit adding an additional power supply and cooling fans. Several months later our company was destroyed by a flood with river water levels reaching 6 feet in our office and engineering lab. We took the E&I amplifier to a car wash, removed the panels and used a high pressure wash to rinse out the oily dirty mess. Once again E&I took on a challenge and agreed to evaluate the unit for us. Something very few companies would ever consider. Within a week we had an answer from E&I. To our amazement E&I had assessed and cleaned out the remaining water and by some miracle brought the unit back from sure death for a tiny fraction of the replacement cost. This is a testimony both to the quality and robustness of the E&I design and without a doubt excellent technical support that this company provides.

Excellent! Thanks for exceeding my expectation. The amplifier arrived Friday, we ran it through our calibration and we were using it Friday afternoon.
