The Tango NP-126 has 2 primary windings and can be
used as Single-ended (SE) to SE, or PP to SE, or SE
to PP.
With
the 2 primary windings connected in series the NP-126
can be used with tubes which internal resistance is
between 10K and 20K. (tubes with lower internal resistance
are always possible) When the primary windings are
connected in parallel the NP-126 can be used with
tubes which internal resistance is between 2K5 and
5K.
|
|
|
Chokes
|
These
chokes can be used as anode/plate chokes and will give
in this application much better sound quality. The "TC"
chokes have a double winding which can be connected
in series or in parallel. Of coarse these chokes can
also be used as powersupply chokes. |
