METASONIX announced the availability of the TM-4 stereo vacuum-tube amplifier, that they claim to be the smallest tube amplifier ever offered to the public.

The TM-4 produces about 1 watt per channel peak power, enough to drive either headphones or high-efficiency speakers. Adapters and speaker cables are included to allow its use with consumer-audio or professional equipment. And it can even be rackmounted using the optional TM-M kit and appropriate rails. It fits right into an MOTM modular synthesizer or into any modular cabinet having a 5U-high standard size. (Unlike every other tube amplifier ever made.)

The TM-4 uses one 6BM8 tube per channel. The tubes are completely enclosed in the cabinet, making it safe to use around small children or pets. The round window displays the 6BM8 tubes, showing them in operation.

Specifications:

Power output: approx. 1 watt peak into 8 ohms per channel at 5% distortion.
Max input sensitivity 0.2 volts for full power output.
Frequency response +-3dB, 70 Hz to 35 kHz.
Power input 10v AC to 12v AC, 50/60 Hz 1 amp at idle–derived from an appropriate plug-in AC adapter. Use of an AC adapter to suit local AC mains power allows use of the TM-4 anywhere in the world.
Inputs: separate phone jacks for audio; unit includes RCA-to-phone adapters.
Outputs: two headphone jacks, 1/8" and 1/4" phone, plus separate phone jacks for each speaker output.
Dimensions: 7 1/2" (192mm) x 4 3/8" (112mm) x 3" (77mm).
Weight not including accessories approx. 5 pounds (2.2 kg).

The TM-4 is hand-made in the USA and carries a 90-day unlimited warranty.
