I finally managed to dig up the specifications for the TX-900 Receiver we repaired a couple of months ago, I had attempted on a couple of occasions to find something reliable, but the best I can come up with are some E-Bay listings which contained the specifications; they are:

• Synthesized Tuner Amplifier
• 40watt per chan RMS @ 8ohms.
• 2 x 2 Channel Output (A+B, Left+Right)
• 40Hz-20kHz with no more than 0.3% THD.
• 30-Station FM/AM Random Preset Tuning.
• Direct Access Tuning Using Numeric Buttons.
• Six Program Inputs Including Video Sound with Logic Controlled Feather-Touch Keys.

This is a great little receiver, and has not failed to provide superb sound quality.
