Bartolucci double C-core Plate-Load Chokes
Sorry, we cannot manage Bartolucci transformers more, please send your request at ricercaesviluppo@mobilia.it
Besides the chokes
listed in the tables below, Bartolucci offers the unique service of winding
chokes to YOUR specifications. The materials that are used for these chokes are
of the same quality as that of their output transformer. You decide which
inductances, currents or DC resistance you need for your projects, if the choke
should be layered etc. and we will have them custom wound for you at no extra
charge.
The induction
value of Bartolucci supply and plate chokes does not change when a DC current is
applied. With several brands the measured inductance can read correct, but with
current applied the inductance can decrease as far as 10% of the actual value.
Bartolucci has rigorously designed all their chokes to eliminate this problem.
Core size and winding techniques have been adapted to offer the best supply and
plate chokes available.

Premium grade 0.1mm core laminations as opposed to the standard 0.27mm grade
(10% extra on standard designs)
A plate choke needs
to meet the same standards as that of a single ended output transformer due to
the wide range of audio frequencies that it has to let pass. Therefore each
plate choke is in fact an output transformer but without a secondary
To find out which
value suits your application fill in the following formula:
fo = desired
frequency
Rp = plate resistance of the tube
Custom at NO Extra cost, single piece can be ordered ! specify
tubes, primary impedance, m/A, working vols (DC), etc.
