Tecnotrafo is back - rebirth of an historic italian audio transformers manufacturer!


... behind the labour of love of the re-birth is my pal Lorenzo Sironi, a passionate music and audio lover and an avid collector of classic theatre and cinema speakers, Cinemeccanica and Prevost being a true obsession and a specialty.

I carefully followed Lorenzo's steps and acquiring and restoring/updating the old machines and materials warehouse in Cinisello Balsamo, (very) near to Milan.

He's young and extremely motivated, humble enough to learn every day and anxious to prove this elusive, rarefied audio world his class, not with hypes and chatting, BUT with his products - i.e. carefully hand wound one by one audio transformers.

I visited Lorenzo's workshop a couple of days ago, on my way to Switzerland.

One stage line preamp... with the 845 mono blocks, Telefunken M15 and Cinemeccanica HUGE horns, will be the workshop sound system.


The sought-after, seldom seen Philips 367 used in the line stage...



Ye olde plant and employees... such an heritage!





... yes... the metal tables and the chairs are the same in the pictures...











The old windings machines... 








Paper isolation, old stock


Copper wires, old stock


E cores layers...

I wish to Lorenzo the VERY best... keeping high quality and no-comppromising in mind.


... upcoming projects? 


A lot... just mouth watering the Western Electric 618B replicas... I'll be the beta-tester and I'll be able to compare directly with the real thing - i.e. my own cherished WE 618B;-)

Contact Lorenzo at www.tecnotrafo.it with your requests... 0,05 mm nickel layers? Bee-wax impregnated trannies? Whatever?

Just ask him.


Stay tuned.
