Metroamp Dagnall C1998 1.5" vs Metroamp Drake 1202-132 2" OT

[frank9310]

1. What are the tonal frequency response ranges and differences between the Metroamp Dagnall C1998 1.5" vs Metroamp Drake 1202-132 2" core output transformers?

2. Since the Drake was used in the 67 Black Flag Plexis and the C1998 was also created in 67, would the Drake sound the same or similar in a 1959 Super Lead as it does in a Black Flag type circuit?

3. Which one would get closest to being able to get the widest range of Hendrix & Trower tones?

I'm interested in any info on this topic also.

Try the search function. the drake has narrower bandwidth and more breakup. its better for blues and the bass circuit. the dagnall is better for the later lead circuit and heavier tones. the drake is great for the earlier hendrix tones and well as doyle bramhall 2

Thanks Roe. I did read all that before I posted. That still doesn't say much to me. "Narrower" is a broad term and not based on anything scientific other than what it sounds like to him. I've read reviews of music gear from guys that are hugely different and incorrect. So to accept that one person's description understand it, we need to first understand what is the actual frequency response of the Dagnall and the Drake are. I was just hoping that someone who specs them out to Heyboer to clone would know something and chime in.

I did find this one other thread since posting that has some decent general info but again, no actual Frequency Response specs or even a general description of tonal characteristics on any of the clone builder sites. http://www.vintageamps.com/plexiboard/v ... ass#p56083" onclick="window.open(this.href);return false;

But frequency response specs won't tell you whether or not you'll like the sound of it, or even what it will sound like. The way the primaries respond affect the tone as much as the abilities of the secondaries to reproduce a signal.

[frank9310]

Maybe so, but it would be nice to see some kind of graph of the resonant peaks and and to know the frequency range just like when you see for example specs on the Celestion site for their speakers. On some you can hear samples of what they sound like with a certain type amp and guitar etc but then when you know for example a sound you like such as a Vintage 30 speaker having a range of 70-50000Hz and a resonant frequency of 75Hz kind of gives an idea that another brand speaker in this range would sound somewhat similar compared to e.g. a Celestion G12H30 with a resonance frequency of 85Hz which is known to be a bassier sound or a Greenback that has a 75-5000Hz FR with a 75Hz resonance frequency is going to tell you without even hearing it that it is a tad less low end than the Vintage 30 and then to see the graph shows the type response such as heavy on mids, even, highs etc.

This all of course pre-supposes that these transformers would all be used on the same circuit kind of like this OT shootout did which is a step in the right direction. http://magneticcomponents.net/HearWhyBu ... romUs.html" onclick="window.open(this.href);return false;

Interesting.
On my computer speakers surprisingly, the Merc Mag OT sounded muddy.

I liked the Magnetic Components best followed by the Weber.

Here's a clip of a Metro head equipped with the 2" Heyboer OT. Marshall Power Brake, amp flat out dimed w/Volume II at 12:00, ran through a '73 Marshall bottom cab with 55Hz G12H-30 Greenbacks.

Unfortunately I've never seen anyone offer detailed specs or graphs of frequency response for their transformers.........not sure you'll get much along those lines, which leads back to user comments as your only source of info.

I thought the Merc sounded muddy at first, but as the clip progresses you hear a darker tone with less upper mids/treble

I would say I liked the Weber best, then the Magnetics Components, then the Heyboer, then the Merc last.

Hey that's exactly why I went with the Magentics Components transformer. Not only did they prove that their manufacturing processes were far superior to anything else out there, die to their exact winding machine consistencies, but they also use the original paper bobbins where MM uses plastic bobbins and not vintage processes.

When I saw the 100 watt output transformer the day it arrived, I began to drool by it's construction. I pulled out the 150 watt transformer from my Bugera 1960 and installed it and it went from a hi-fi sound to a rip roaring Marshall Plexi a'la JMP circa late 60s-early 70s sound with think, fat articulate notes that just screamed JMP Plexi!

I also just snagged a new Marsahll Vintage Modern 100 watt head based off the JTM45/100 circuit which was designed by the same guy at Marshall who created the new JH100 Hendrix hand wired stack and I have to say that as amazing as it sounds, I'm now running that same Bugera in stereo with it because the fat lead tones it gets now with the Magnetic Components transformer. So I have this killer Marshall VM with KT66 smoothness mixed with this ultra fat EL34 lead tones from the Bugera and without question it was due to the new OT from MC.

To boot, the guy at MC sent me the full specs no problem and answered no less than 20 questions before I bought it and followed up with me many times AFTER I bought it! Made in the USA baby Oh yeah!

[Structo]

Who did you buy the MC tranny from? Triode?

Seems like there is only a couple dealers, the ebay store and Triode.

They sure do have decent prices on them, that's for sure.

Good to know they also sound good! That is always a plus!

[frank9310]

Ah no I got mine from CEDist.com which I think is also the same company as tubesandmore.com

[Structo]

Ah, so you have a commercial account with them.
I tried getting on CE one time but they started asking for business ID# and stuff so I couldn't do it although I have a small side business of amps and guitars but nothing on paper.

In looking at their site, I don't see how you can tell if they are MC trannys?

I see Hammond and Marshall but nothing that says it's a MC.

[frank9310]

Hey they didnt ask me anything. I just told them I sold effects pedals and they said ok what do you want!

The ones on their site that say fo JCM 800 is the MC o you can email them and ask them. The guys name is Joe info@magneticcomponents.net

He told me which one to get. I htink its the same as tubesandmore and some guy on ebay sells them too. I think the guy on ebay sells them for the same price you can get them for at CE.
