TK 7441 also know as TH 4663 /
TK4519
The primary impedance can be configured
for either 2k3 Ohm or 3k5 Ohm by means of
links and is rated for 100mAmp DC but can
be increased to 130m Amp maximum.
The
secondary is made up of four, 1 Ohm sections
which can be wired for either 4, 8 or
16 Ohm speakers.
Total rating, 30 Watts at 40 Hz
Insertion
loss : 0.3 dB (16 Ohm connection).
0.5
dB, 30 Hz-30k Hz (from 3k5 Ohm source,
8 Ohm connection).
Operating
Range : 10 Hz to 80k Hz.
Primary
Inductance : 22 Henry (20 Henry min) at
10 Volts, 50 Hz, 100m Amp (or, 32 Henry
at 200 Volts, 50 Hz, no DC).
Primary/Secondary
LL : 13m Henry at 1 Volt, 1k Hz.
Dimensions
11 x 11.5 x 13cm high.
Supplied
with a diagram for the connection options.
Some
remarks from Sound Practices No. 1
Partridge TK4519: Delicate
and detailed highs, smooth accurate midrange
and fast extended lows. The Tonal balance
was right on the mark. Maybe the best
full range sound heard from a single 300B
to date
