Pushpull Tube Amplifier, 437kb

25WPT Monoblock PushPull Tube Amplifier:
Not available at this time, upgrading.

Albert, Dallas, Texas "I honestly did not think the sound would improve with the new amps...but WOW! running mono right now and its as live as it gets... Albert"

The 25WPT monoblock pushpull tube amplifier is 25 watts of pure class A delight. The 25WPT incorporates no global feedback. The tonal balance, spaciousness, dynamics, imaging, layering, true micro-detail, and speed, means music sounds lifelike. The 25WPT tube amplifier has only 2 total stages. I also incorporate a 3 position "tonal balance" switch that can be adjusted on the "fly" for better flexibility when matching to individual systems.
