The Tube Head Pre Amp is the entry level into what they're calling "Audiophile Miniature". Honest to goodness audiophile sound, in a miniature package for a remarkably low price. The Tube Head uses a single 5670/2C51 tube on the input stage which helps eliminate any trace of digital harshness and imparts a healthy dose of tube magic to the sound. The tube head is perfectly matched with the Big Joe Power Power Amp, and is equally at home when mated to power amps costing many times more. With the auto bias adjusting hybrid circuitry there is no need to adjust the bias or try to match the tubes. As with many of the Firestone products the Opamps are changeable allowing you to tune the sound to your particular taste.

The Tube Head is a dual-chassis, double-decker design with a separate power supply linked by an external DIN cable. On the black anodized, front panel are a volume knob, input selector switch and the cool Tube Head graphic. The rear panel features two sets of RCA inputs and one output, in/out jacks for the power supply and the on/off switch.

No cheap plastic here! The Tube Head Pre Amp is manufactured with a solid aluminum chassis and features a black anodized aluminum face plate. The volume knob is also machined from solid aluminum for a high quality look and feel.
