Low-power
AUDIO AMPLIFIER IC
(type MC34119P)
A low power amp that may be used with
two to six volts DC. Drives an 8 ohm
speaker and up; maximum output power
is 1/4 watt. Adjustable gain up to 46db,
minimal external parts required. This IC
is very useful in small, portable battery-
powered circuits

NOTE: The IC’s in this product group
are packaged with pinout information
and a circuit diagram. Your stocking
distributor has a detailed manual so
that you may photocopy technical
information, circuits etc. .
STANDARD TOROID CORES
Useful for inductors in HF
and VHF circuits, these
are donut shaped cores of
pressed ferrite; typically hard to find.
WIDE-BAND
TOROID CORES
Use for inductors and
wide band transformers.
Use for antenna matching
etc.
0.80” Type T-80
Toroid Core
Type T-80 is 0.8” diame-

“White” Toroids
These toroid cores are very commonly called for in radio
matching circuits, QRP transmitters and receivers as well
as radio frequency amplifers. These are color coded with
white enamel. 1MHz – 25MHz. Tempature stability 30,
Magnetic tolerance +/- 5%.
Toroids are packaged one per display package.
