Huh,... I too have a pair of ''new'' unused Carver monoblocks, it is the Silver 9T from Dec1992, 120V, made in USA, with black acrylic platform, original cartoon box, bought at SoundCity dealer(NYC).
They are really never used(except 30 minutes in 2003 for testing), since then I turn on then every sunday at 60Volts for capacitor charge.
Anyone interest in buying?? (sorry it is not a tube amp, have 10 pairs of Toshiba output transistors).
