The Wright Audio
Oasis Monaural Power Amplifier

 


Carefully designed, the Oasis Monaural Power Amplifier maximizes the potential of vacuum tubes by demonstrating rich musical harmonics, correct attack and decay times, vivid resolution and a spectacular soundstage. 

The amplifier can accommodate KT88, 6550, KT77, EL34 and 6CA7 output tubes. 

Power output is 50 watts when using KT88 or 6550 output tubes.  Individual tube bias adjustment is easy with pushbuttons and controls next to each tube with direct readout on the front panel milliammeter.  Like all Wright Audio's amplifier products, there are  no circuit boards for ease of repair or future upgrades.

The power transformer is a custom, low-impedance design for maximum power transfer to the output tubes.  There is a separate power supply dedicated to only the input tube, proven to enhance sonic clarity.

For the correct gain, lowest noise and  overall best sound, the Oasis Power Amplifiers are only available with the LT-6P Preamplifier as a perfectly matched set for a complete, no-compromise amplifier system.
