Abstract

The present invention provides a device with rear-mounted vacuum tubes, comprising a protective cover with a plurality of heat dissipating holes, a rear panel with a panel opening, and at least one vacuum tube, wherein the vacuum tubes are arranged in a containing space of the protective cover through the panel opening and inserted to a connection circuit board for coupling to a printed circuit board. In addition, the protective cover, the rear panel, and the vacuum tubes are placed in parallel with the printed circuit board, so that heat dissipation for the device is improved and replacement and maintenance of the vacuum tubes are easier. In particular, a vacuum tube audio amplifier apparatus having the device with rear-mounted vacuum tubes as disclosed herein can be stacked.
