Congratulations, you seriously damaged this item. You must not, never ever use an Ohm meter. You just magnetised the transformer. It will not have the performance it should have.
These things are worth loads of money, my memory of them was sounds good but hum could be a minor problem if placed near other equipment with big transformers, amplifiers mainly. This is a brief spec. Recommended cartridge impedance < 10 Ω Gain 27 dB at 1 kHz Frequency response 10 Hz - 100 kHz (-2,5 dB +0,5 dB) output loading 47 kΩ // 200 pF You would not expect 50mV output as this would overload the input RIAA pre amp. Many amplifiers of the day would overload to clipping the input at just 30mV in fact the Leek Delta 30 was only 20mV. A good MC cartridge would only put out about 0.5mV or even less. The transformer would up this to the 3mV or so that most MM inputs needed.
Interesting as always. That really is some enclosure! When I saw the picture I thought you might be working on one of those arcade strength testers - see how long you can hold on! I guess a small box with two transformers inside would be a tougher sell.
Nicely repaired and tested simon :-D I think i would want to put a blob of rubber solution on the solder joints to the wire outer insulation. To try and stop the copper core snapping through vibration. Not too smart for the manufacturer to forget simple stuff :-(
Ortofon Make Some Really Nice Kit I Don't Have Any Of Their Moving Coil Cartridges But i Have a Mono 2Mse Moveing Magnet And a 2M Black Both Are Superb Cartridges Nice Fix On That Teflon Coated Wire Simon I Have An Old A&R Mc10 Step Up Pre Amp For Moving Coil Cartridges But They Say You Get The Best Sound Useing Transformers !!..Regards mike.
Can't see why when you tested it's resistance on the output with the multimeter was quite significantly different but on the the scope shows matched per channel how come this is the case. Why didn't you match the output with a resistor
@@SoddingaboutSi I'm not convinced by that argument, it makes it harder to set up the cartridge channel separation if it's out of balance. of frequency? but a cartridge works at a lower resistance than that a couple of Ohm's difference is quite a lot in the scale of things
Don’t you know you can only open those cans on a small island located on the equator where the earths magnetic flux is at its minimum on the second Wednesday of the first month in a leap year. Don’t you know that by even look at it you have entered Quantum superposition of states with decoherence! Bloody amateur!

What a uneducated answer. I have pinned it for others amusement. Thanks so much for commenting.
You caught the first audiophool of the year! Some people have all the luck!
It has tunnel diodes in it. Oh hang on, it doesn't..
Super video. Very well explained. Speaking as a technician myself, this is as good a demonstration as one could hope for. Very well done.
Thank you very much! And thanks for watching.

Thanks Simon very interesting and informative as usual. Great video thanks for sharing. Best regards Chris

Especially when this thing retails for 1800 Euro.
@@douro20 That's just over 1500 pounds!!, dam expensive for two transformers, a box and metal cups.
Someone is taking the micky.

certainly an interesting bit of kit.
Cheers George.
I am quite keen to buy one of these but it's difficult to see where the 2,000 euros is?
@@Dobbs65 thanks... I bought one hahaha. haven't set it up yet. waiting for some repair work to be done on my TT.
I was hoping you would show the inside of the cans; and how this thing works as a transformer; with the two cans so far apart?
They are just trasformers. Not much to see other than a few turns of wire. Too fragile to risk disassembly.
because theres two independant ones for stereo
seems like a design flaw having such fragile wire, for the price you'd hope for more
@@markbuxton2368 Thin wire is essential in its design in order to fit into the core, and it is exactly why it's expensive!

Good question. But at this frequently it would make little difference . I take it you were asking a question? I saw no question mark:-)

of frequency? but a cartridge works at a lower resistance than that a couple of Ohm's difference is quite a lot in the scale of things
John sweda, D.c resistance and a.c impedance are not the same thing.
@@zx8401ztv Exactly. DC resistance was just used to test continuity. I would have expected them to be exactly the same, nut their close enough.
@@zx8401ztv I'm always surprised by how many people do not know the difference between resistance and impedance.
