Excel Sound Corp ST 1 step up transformer


Hello!
Anyone here with any information on this step up? The exakt description is;

Excel sound corporation Super ST 1 MC transformer

I am now playing it on my Kuzma Reference 2, 4-point 11,5 inch arm, My Sonic lab excellence ex and an excellent swedish phonoamp Simply Black phono and its sounds so good! I have asked the manufakturer in Japan about specification but they have none?!

Add link, you can’t add phono on audiogon, this forum is oldschool.

@persve

Here you go -

From the specs it appears to be an outstanding transformer, hard to beat today - which would explain the sound quality you are experiencing. Look at the bandwidth and accuracy -

  

■ Primary impedance Low 2Ω / High 40Ω 
■ Load resistance  47kΩ 
■ Boost ratio 
■ Frequency band 5-100,000Hz 10-50,000Hz ± 0.2dB 
■ Channel separation 
■ Total harmonic distortion 
■ Weight 
3.3kg ■ Dimensions W12.2 × H14.0 × D23.0cm 
■ Release 1980s? 
■ Discontinued 
■ Remarks With connection cable 0.8m.




Wow! Thank you so much! This info makes me so Happy! Thanks again!
Best regards from Sweden

Dear @persve : Maybe your SUT is even better to this one that Excel design and manufacture for Etsuro and that's very expensive unit:

So, congratulations for the unit you own.

Regards and enjoy the MUSIC NOT DISTORTIONS,

I am in the market for a step up transformer.   This looks like a good one, anyone know where I can buy or audition one?

Based on comments by Chakster, Dover, and Raul, this appears to be an obsolete unit, maybe sold in the 1980s, and very rare; the OP lives in Sweden. So you’d be very lucky to find one, let alone audition it. Raul suggests that the modern equivalent may be available from Etsuro.
