What is Frequency Response?

What is Frequency Response?

Most of us know what frequency is; the high or low tones of sound. But some have asked what frequency response is and how it relates to transformers.
The Voltage Dilemma

The Voltage Dilemma

Custom design a XPWR transformer with a number of outputs (secondaries) totaling 300VA. Let’s say one of the outputs is 6.3Vrms (all future comments will be rms Volts) at 5A. In addition, don’t let...

I purchased Edcor transformers for all of my amp projects for many years. Quality VS price? Edcor satisfy me every direction. Not even single transformer failed in the past. I'm so happy and confidence to using Edcor transformers.

Used this transformer in a custom 20W single-ended power amp and I couldn't be happier. Great value and great sound!

I used this transformer as a ground loop isolator to interface a digital guitar rig with a traditional tube amplifier. I am super impressed with the 20Hz-20kHz response and ultra low distortion. After trimming the leads a tiny bit ..it fits inside a small 1590a enclosure. You can see it in the top right of the included image.

I build HiFi tube amps and these work well for more than just Guitar amp applications! They hold their own against much higher priced transformers.

I used these for a passive color box project, and am very happy with the way the device sounds. I was not particularly familiar with this brand prior to the project and I am sure that I will be using these again. Out of all of the color boxes that I have built, this one may be the most transparent so far.
