t.bone SCT 800
Cardioid Tube Condenser Microphone
The t.bone SCT 800 is an inexpensive tube microphone with a fixed Cardioid polar pattern.
Like most such mics, it uses a 32mm K67-style capsule and a circuit very similar to the Apex 460 (albeit without pattern control).
Unlike the Apex 460, the SCT 800 uses a single circuit board. It is a dual-layer board, likely with through-hole plating, which makes desoldering components (for modification) somewhat more difficult. The 12AX7 tube is socketed.
Its published specifications are unusual, if accurate: the mic’s claimed sensitivity is extremely high at 48mV/Pa, and its self-noise is extraordinarily low at 6.5dBA. The high sensitivity gives the mic relatively low headroom; its max SPL is just 112dB (1% THD).
The mic’s nominal polar pattern (measured at 1kHz) is wide cardioid, with no distinct null at 180°.
The mic ships with its power supply, cables, and an elastic shockmount in a padded flightcase.
