The Toshiba ST-335
MkII is an AM/FM stereo tuner featuring a stereo beacon, a three-position LED
FM center channel tuning indicator, a five-step LED signal Strength/ AM tuning
indicator, and a record calibration (Rec Cal) tone output for pre-adjustment of
the input level to a tape recorder. The record calibration output is 6 dB below
(-6 dB) the output level from a 100% modulated FM transmitter. The FM center
channel tuning "meter" consists of a two yellow LED s flanking a gree
LED; optimum tuning is attained when only the green LED is lit. However, tuning
is relatively broad in the 'green range", and distortion and separation
values might vary from our measurements. The output is provided by two
"patch cords" with phono plugs, approx 1 meter in length.
The FM pilot
leakthrough is relatively high and a recorder's MPX filter must be used when
making recordings from FM stations.
