"I just ordered one of your transformers because of the great "About Us" page you did up on explaining how you make them. Incredible! The sound clips clearly beat all the others especially on the last couple notes on the Heyboer vs. yours. There's more upper mid harmonics it seemed like. Thanks and can't wait to hear it!"

The Background: The following sound clips were not produced by us or for us. We happened to find these on an independent forum that was not in anyway associated with our company. In fact, Curt Granger of Granger Amplification did this independent comparison of 4 different transformer manufacturers himself to satisfy his own curiosity. He did not even know at the time that the unidentified brand that was sold through a well known distributor were made by us at Magnetic Components, Inc. (Now known as ClassicTone part number 40-18025). He used the transformer manufacturers Weber Magnetics, Heyboer, Mercury Magnetics and ClassicTone by Magnetic Components, Inc. (Us) for his comparison. We were recently granted permission by Mr. Granger to use these sound slips.
I would like to thank Curt Granger of Granger Amplifiers for his fine work on this thorough and unbiased comparison. Also, I would like to thank him for his permission to use his sound clips for this comparison. Please see Granger Amplifiers to check out his fine amplifiers at http://www.grangeramp.com
Note: Please let us know which you think sounds better and why at magneticcomponents@sbcglobal.net Please tell us your first name and where you are located at minimum in your correspondence. We may publish your opinion on our website.
Conclusion: You make the choice!
Transformer electrical rating differences: According to Mr. Granger, all were close in their ratings with the exception of Mercury Magnetics having a slightly smaller DC resistance than the rest.
Transformer construction types:
Weber (bobbin wound), Heyboer (Distributor: Mojo) (paper layer wound), Mercury Magnetics (bobbin wound), ClassicTone by Magnetic Components, Inc. (ours are paper layer wound!)
Recording settings and methods used: The same for each recording
Recording Equipment Used: Roland VS1680, Behringer B1, dbx386
Guitar Used: Gibson Les Paul Standard
Amplifier Settings: All straight up the middle (12 O' Clock) with Lar-Mar master dimmed (to be truer to non-master "Plexi" sound).
Amplifier Brand Used: Granger Model M50 Plexi with 2 X 12 Cabinet
Mr. Granger verified that the only thing that varied in the recording methods and equipment were the transformers themselves. He even tried to duplicate the guitar riffs from each recording to the best of his ability to help in the comparison.

The "OT Shootout" (Output Transformer)
"I have read and have been told by many knowledgeable and reliable sources within the amplifier industry that paper layer wound transformers (a.k.a. paper tube, paper bobbin, etc.) are better because they help provide an amplifier with that ultimate tone. They mention that the sound of amplifiers using paper layer wound constructed transformers from the vintage era of the 1950's and 1960's are preferable to modern era, nylon bobbin constructed transformers due to their outstanding tonal characteristics. Even though I am a little biased as President of Magnetic Components, Inc. and we still predominately manufacture our transformers using this fine, traditional, time honored method of winding our transformers, I must admit I was a little skeptical as well.

Well...after hearing the sound clips, I can now definitely say that amplifiers using paper layer wound transformers resoundingly sound better. In my opinion, our transformers in particular sound the best. Please don't take my word for it, hear why I think ours sound better."

Hear for yourself and you decide!
Myth or Fact?
"Amplifiers using paper layer wound transformers have much better sonic and tonal characteristics than the modern era, nylon bobbin wound transformers."

What others are saying: See following
“I saw these clips on another forum and was really impressed with the quality of tone from the transformer. Along with some other forum members, we searched out to find that this iron was made by Magnetic Components. I then contacted them about some custom work and became a customer. Being an amp builder who has used other transformers, I was really impressed with the tone, and sweet vibe this iron has. As a result of these clips, I became a customer and use this Iron in my EL34/6L6 based amplifiers!!!"

About the 50W Tranny Shootout.

Weber: Dark, and particularly Gritty

Heyboer: What we've all come to expect a Marshall Amp to sound like, All the "Bite & Kerang."

Mercury Magnetics: Well Balanced, & Very Pricey.

Magnetic Components: Balance w/ Bite, What A Deal!

Mr. Janisch, A 50 Watt Transformer Bundle from Triode Electronics NOW sounds like a Good Deal, Literally!

As to myself: 33 Years in all manner of Electronics. Tube to Solid State, Analog to Digital; Consumer, Industrial, Two way Radio & Broadcast. And not to mention: Musical Instruments & Amplification. Glad I could participate."

Dollar for dollar you’ve developed the best output transformer on the market today!

I’ve reviewed the clips at least a dozen times for each tranny and have come to these conclusions.

Weber – dark and buzzy. There’s a certain annoying frequency that would need to be eq’d (cut) in the studio.

Heyboer – open, woody and bright. I personally found it too bright at times, to the point of being too trebly.

Mercury Magnetics – stiff and dull. Sounds like a heavy blanket covered the speaker!

Magnetic Components - A perfect blend of open bloom, woody and responsiveness. Paper makes the difference!!!

Congratulations to the Magnetic Components team on creating a true gem!!

Regards,

Sam P.

After hearing the four different transformers, it was surprising to hear how well your product sounded against the premier products in the business. I really liked the character and girth that your product delivered, very tough to decide between the Heyboer and yours but given the construction and price it’s a no brainer for anyone wanting to upgrade a tired old tranny in an amp.

It was interesting to me that my favorite of the four was Magnetic Components. Heyboer was a close second, but I prefered the balance and sweetness of the Magnetic Components. It seemed juicier and more natural in nature.

I saw and played your new sound bites page with my favorite OT and was pleased to see the responses. Well, yeah!! If you have ears on your head!! I am very happy for you in this business that people are 'getting' your product. It only makes sense to me, of course.

At first I liked the CT the least.  It had the least "fat" in the lower
midrange, and it had the most "fizz" on the top.

Then - at the Journey tune - the Mercury started to bother me - it has a
peculiar harmonic structure - or the guitar is a little off tune -
something's not right.

The more I listened, the more the Heyboer started to bug me, but not as
badly as the Mercury (I still wonder if the guitar had a tuning problem on
the Mercury).

With the Weber, the harmonics sound more like they belong there.

Then I went back to the beginning.

Yep, the Mercury lacks overdrive and "just ain't quite right".

The Heyboer has too much upper mid - there's stuff that just doesn't belong
there.

With the Weber, the more I listen, the more something is a bit off.

In spite of the fizzy top, the more I listen to the CT, the more 'right' it
sounds - more musical.  But then again, maybe the guitar was just better
tuned.

So within the parameters of this test, at worst you make a good sounding
transformer at a great price. At best, you make the most musical sounding
transformer at a bargain price. Kudos.

If I have the time, perhaps I'll listen to these again through my good
system, though I expect that the results will be much the same.

Weber, quite a full bottom end, maybe too full?

Heyboer, very smooth and creamy overall

Mercury, Oh dear!! Dreadful!

ClassicTone, so close to the Heyboer, in fact, too close to call!

So overall, the ClassicTone has to win because it's an absolute steal for the price!

Buy one today!
