Best contact Ortofon in Denmark and arrange through them (unless you bought through a US dealer).
They will send you another one on receipt of the damaged one.
Charge you replacement cost for it though - compare with Japanese price for new.

I believe the $5000 Swiss-built "Magic Diamond" cartridges use the SPU motor assembly - and weren't EMT cartridges also based on Ortofon?
Truly the Momma and Poppa of MCs.
Brian.

...but whether it would be a better match to your speakers than the SPU who's to say.
I am planning an SPU Mono vs CG 25 comparison in my system in the fairly new future. Unlike your speakers mine could do with a little help in that area.
Maybe...

I use S&B TX102s which have huge cores but my system does not allow examination of the subterranean levels.
I mention the magnetic solution only as an alternative to resistive attenuation. How it is implemented is another game of pinochle.

[quote user="Romy the Cat"] the passive linestages (resistors)tend to be more transparent then active stages but it is only in the case when a passive line stage (attenuator) sits right next to the grid of your input tube. As long as a passive linest...

Well, you could do just that - just plug and unplug. Couldn't be purer than that ;o)

Do you REALLY need one?
Why SHOULD you need one?
A buffer is "simply" a device for converting impedance from high to low to drive cables but every such device loses information in the process.
With a 47R ouput impedance surely your Bidat has ...

Romy, a true old-fashioned mono cart, like the Ortofon C Series, has NO vertical compliance at all so theoretically could cause heavy damage to a stereo trace. However I am in correspondence with a chap who does play SOME old stereo pressings with a ...
|

SPU alright! White/Blue and Red/Green should carry identical signal so either pair will do.
The advantage of the SPU Mono is, like with the DL-102, you need have no worries about damaging stereo pressings.

If it is the CG it should say Dia 25 somewhere - unless it is for 78s when it would say Dia 65.
"Dia" for Diamond, the number for the diameter in microns.
I guess if it doesn't say this it will be the SPU Mono.
Actually, if you remove it from th...

NOT like the '102, which has just the two pins of course.

Romy, is that an SPU Mono that you have there? This converted stereo cartridge (SPU = Stereo Pick Up) has its coils rotated 45 degrees to reduce vertical sensing.
The Ortofon C Series are the genuine mono cartridges - the motor system is the same ...

Another Ear Academy course ahead for me then.

My reference to air caps was purely a tongue-in-cheek reference to the voids in the coil. Of course the parasitic capacitance due to the propinquity of winding layers would dominate and here the dielectric is quite often Mylar.
It's just that the ...

Hello again KIS
With unbypassed cathode resistor the input ECC83 is giving a gain of 30, adding the bypass cap boosts this to more than 60 thus gain will have more than doubled.
I can't try this mod yet because the 834P currently in my system i...
|
|
Hi KIS, by adding the capacitor you have
doubled the gain of the first stage therefore driving the grid of V2 harder, meaning increased distortion
and
added another source of colouration.
Louder tends to be interpreted as "better" in show...

The thing to remember about commercial speakers is that they are designed to compete in the showrooms so must shout "Here I am! Listen to me!" above the tumult of the market place.
Brian.

Yes, keep it simple.
Products made for sale in showrooms are loaded with bells and whistles to impress and dazzle the gullible. More stuff for the salesperson to browbeat customers with.
Also manufacturers like to throw their net wide to maximize t...

Hello Romy A sleepless night had my all-but-derelict brain going round and around the phono stage and, of course, more questions than answers were thrown up. Did you and your designer friend first try an intermediate version of the 834 circuit which ...

I don't think it is possible to deconstruct as you desire. Perhaps you need to talk to Per Winfeld at Ortofon (I can give you the email address).
The SPU Mono has 4 coils rotated 45 deg and connected for vertical modulation cancellation. The CG 25...
