Vintage Tube Mono Amplifier Acrosound TO-300 Ultra Linear Hi-Fi Amp w/ Wood Case

Rare vintage custom-built vacuum tube mono amplifier featuring a highly desirable Acrosound Ultra-Linear TO-300 output transformer along with Raytheon transformer components. Likely dating to the 1950s hi-fi era.

This amplifier was previously paired with a Garrard turntable as part of a vintage custom mono hi-fi setup.

Included is the original/custom wood cabinet featuring an open-sided ventilation design, giving the amplifier a fantastic mid-century custom hi-fi appearance. Also includes the vintage cables shown in the photos.

A very interesting piece of early high-fidelity audio equipment with strong appeal to vintage tube audio collectors, restorers, and DIY hi-fi enthusiasts.
