Welcome to Ricerca e Sviluppo - Bartolucci Transformers
Giuseppe Bartolucci
Thanks to the participation of Giuseppe Bartolucci,
Ricerca e Sviluppo S.a.s. is a firm
specialized in the production of transformers set to satisfy every
kind of need.
Since 1970 Bartolucci is in the domestic and
international market and it supplies
the most important company of the sector. In order to offer to customers always
the most forefront solutions Bartolucci, in the Ricerca e Sviluppo Sas, is the
responsible of the technical sector, and makes every effort in the continuous
research of the most updated technology to always realize the ideal transformer.
Bartolucci's Double C Core transformers is the result
of more than 35 years of experience in the
planning and production of high quality transformers. These are craft made
transformers created by Guseppe Bartolucci & Co
in Italy at Ricerca e Sviluppo S.a.s..
Giuseppe Bartolucci’s purpose is to obtain high performance with a well balanced
support of high technology, know-how and art. Bartolucci believes that producing
high quality transformers does not mean only to put together excellent materials
or optimizing the different technical values. Certainly, these are important
elements in order to obtain an high performing finished product, but surely it
is not enough. Technical specifications or expensive material aren’t sufficient to
explain the sound qualities of a transformer. The challenge is to find an
excellent combination between technical variables, that sometimes are rather
contradictory, and the result of a really high quality project. The whole
shebang to offer to a competitive price.
Are transformers all the same?
Many people compare the different transformers on the market giving importance
to the information declared by the data sheet specification of the different
models.
Technical specifications are surely important, but are you really sure to
know all technical specifications could allow you to operate a very good choice
that could really satisfy your requirements?
Many audiophiles are aware that choosing a very good transformer is not only
a matter of watts and distorsions declared by the technical specifications. The
transformer, notoriously one of the most important elements of an amplifier,
who does indeed the difference. Please let me do an example.
How do you have to choose a Power transformers?
It is a common opinion that power transformers do not do great differences on the
finished product. Perhaps because one thinks that is only a matter of ampere
and voltage need.
- But have you ever tried to replace a standard power transformer with a
high quality power transformer in the same circuit?
- Going on: do you ever ask yourself the question why is a Bartolucci’s
transformer two or tree times more heavy than one of the other brands?
Do you ever ask yourself the question why is the efficiency of a Bartolucci’s
high quality power transformer better than 92%? Why is its regulation within the
0.5%? And why do we require to the Cores guaranteed for 2.2 teslas, during the
planning and production a Telsa of 1,00/1,30?
- How does a standard/commercial power transformer work in an audio frequency?
- Or perhaps do you think that audio power transformers have to work
only at 50 or at 60Hz?
- Furthermore: how does a standard transformer react when you put it under
stress in a audio circuit?
- Moreover: what do you think about audio output transformers, about
Interstage transformers, and chokes?
- Does your transformer give you problem of resonance at the high frequencies?
Why? And what are its performances at very low frequencies?
Main features:
- Multiple section and multiple-layer design
- Hand-wounded without stress in order to provide an accurate
interleaving and a correct wire voltage
- Carefully selection of each double C core to reach a high permeability
and a perfect mechanical adherence
- Potted in fine black well finished steel can
- Epoxy resin impregnated
- Full copper connection terminals on some models only
- Every transformer is tested in order to meet the declared specification
- Custom models are available without extra charges even for one item
- OEMs enquiry are welcome
- Very high quality at competitive prices
