Hi All
Looking at getting a new Cartridge maybe MC, but my Phono stage is MM only.
I like the Phono Stage I have so I would need a step Up Transformer, so do any of you here have experience with this
MC to mm Audio Stereo Step Up Cartridge Transformer | eBay
or are there other options at reasonable money out there?
Ps current thinking on a Cartridge DL-103
Thanks
Garry

I think the DC resistance is to high. I would go for a Lundahl or a Sowther...

If you have time.....make your own mc transformer.Couldn't see any mention of the most important parameter - core material. Why would you choose this in preference to a Lundahl or a Tribute?
I made mine without a winding machine. It's easy to do but it's a lot of work. Just buy the best core you can find (probably a cobalt amorph core is the best and cost between €15 and €25 each)

Why not use a head amp instead of a SUT?
AKSA (who have their own forum on these pages) offer the "Paris" head amp - JFET-based, battery powered. You can find details here:
::: Aspen Amplifiers :::
(scroll down the page)
I have one - IMO it's one of the best. It's also replaced SUTs for a few of my friends. (And despite what Hugh says in the blurb, it was called the "Paris" ... because it "gives good head"! )

I have no promlem doing a build, Have you got any plans?

this looks interesting, but still pushes the budjet

I am a huge advocate of good step-up transformers, and it's what I use. But... not here. The DL103 has a large DCR for a moving coil (50 ohms or so). That means you can have losses in the treble due to the leakage inductance of all but the very best (read: expensive) SUTs. I would second the use of a transformerless head amp. IMO, a bipolar transistor input is a better solution than an FET for this application, but I gather that you're not going to do your own design or a scratch-build?
The right material Metglas magnaperm 2714AFI have no promlem doing a build, Have you got any plans?

or you can use from Vacuumschmelze the 6025F (=the same as 2714AF)
This firm sells it:
MES Manz Electronic Systeme OHG | Softmagnetic products | Semiconductors | Busbars | Military and Space | Heat sinks
or the 6025F:
Online Catalog & Consulting
I used the 2714AF (MP3210P4AF) 40 primary windings and 600 secondary windings
An externally hosted image should be here but it was not working when we last tested it.
sure I worried but after all the bandwidth is about 300KHz.
Sekels have a smaller core I just saw:

Not worried about high inter-winding capacitances in a toroid ?
Also the second link for th 6025F did not return an item for purchase, despite registration ....

Could you elaborate about tourns ratio for several gains and wire type? I need 1:10 20dB for a Denon DL103R?
I can open the links i sended, i don't know if more people here cannot open them.
You find the Al-value in the links also so it's easy to calculate the minimum windings required.
btw what else you want to know?

40-turn primary / 600-turn secondary is 1:15.
But this is only more parameter out of many ....

The Denon DL-103R has an impedance of 14 ohm.
Would your above example in post #11 be suitable ?
What would be the typical leakage inductance ?
Should a shield be put on the outside ?
I am total idiot with transformers, so apologies for stupid questions.

The 103 is spec'd at 40R, and the samples I've seen were closer to 50R.
You are absolutely correct with the DL-103 :
Denon DL-103 Phono Cartridge
The DL-103R, however, has different specs :
