IM IF Amphliur By adopting three le,
a crystal filter and a block filter, the TU 999
achieves an Ideal IF characteristic far be
yond what is poss:ble through the use of
a Single crystal filter. The result is a great»

ly improved distortion factor. and equally
better stereo separation and phase charac-
teristics at high frequencies when the tuner
is receivmg stereo Signals

Anvmic-d I'M I . lll"'id Three low neise
MOS FETs are employed for the two RF
stages and the mixer stage. Combined
with a 4 gang variable capaCItor, they en
sure an exceptional sensitivity figure of

improved intermodulation distortion factor
as well as enhanced image and SN ratios.

of meters aid in achieving preciSion tuning
of FM signals with the TU-999. One indi

The TU 999 adopts an LC type filter for the
multiplex carrier leak filter Endowed With
a sharp cutofi characteristic. this filter com-
pletely prevents carrier leakage so that heat
interference and consequent intermodula
tion distortion have been drastically re-
duced
