Toshiba ST-335 MkII tuner

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.
