The Pine Tree Audio FireTiger is an ultra high-performance 6SN7 and EL84 based stereo power amplifier designed for systems utilizing speakers with sensitivities of 90dB (1W @ 1m) or greater. The FireTiger provides a wide frequency response, very low distortion, and the quick transient response needed to excel with any genre of music (including both highly dynamic and heavily compressed). 

The dual chassis design makes for a virtually inaudible noise-floor due to the isolation of the toroidal power transformer and other power supply components in the power supply enclosure. This allows the audio circuitry to be physically separated from the power supply with the 6 foot, locking power supply output cable.

The circuit design of the FireTiger was created to provide the characteristic warmth and richness associated with single-ended Class A vacuum tube circuits and also realism and dynamics associated with wide frequency response of today's high-performance amplification. The result is a sonically captivating amplifier that makes music listening a more enjoyable experience. 

A unique feature designed to prolong tube life are the dual switches on the power supply enclosure. On the left hand side is the Warm-Up Switch which puts the tubes in a warm-up mode. After approximately 30 seconds the Play mode switch can be activated and music can be enjoyed. The power down procedure is just the opposite (Play mode is turned off, wait 30 seconds and turn off the Warm Up switch).

Gold-plated RCA input connectors and 5-way binding posts are located on the back panel of the amplifier enclosure as well as the power supply input receptacle. On the back of the power supply enclosure, the IEC inlet, fuse and power supply output connector are located.

A preamplifier or source with output level control will be necessary with the FireTiger as it is configured as a pure power amplifier (with no level control). The FireTiger is easy to drive with its high input impedance and sensitivity of 500mVRMS (0.5 Volts) to develop full power into 8 ohm speakers. 

The FireTiger amplifier will make an excellent pairing with your sensitive speakers and provide the richness, depth, stereo separation and ultra low noise that will enhance the enjoyment of your listening sessions.
