Engineering and use context

It uses two 2A3 output tubes and two 6SN7 drivers. Bias is adjusted automatically, and easily reached fuses protect the amplifier if a power tube fails. Three RCA inputs are fitted, with an optional pre-in, and the feet are anti-vibration designs chosen for its mass. Eight colour finishes are offered, and a remote control and tube cage are optional.

With only a few watts available, the Mira Ceti suits high efficiency loudspeakers.
