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.

A device with a rear-mounted vacuum tube, comprising:
- at least one protective cover comprising a plurality of heat dissipation holes, a containing space and an opening edge;
- a rear panel comprising at least one rear panel opening, the opening edge being joined to the rear panel opening;
- at least one PCB (printed circuit board) electrically connected to at least one vacuum tube;
- and
- a transformer electrically connected to the at least one PCB, wherein the transformer and the at least one vacuum tube are arranged at opposite sides of the at least one PCB;
- wherein the at least one PCB is mounted to the rear panel opening, so that the at least one vacuum tube is arranged within the containing space of the at least one protective cover.
A device with a rear-mounted vacuum tube, comprising:
- a plurality of protective covers, each of the protective covers comprising a plurality of heat dissipation holes, a containing space and an opening edge;
- a rear panel comprising a plurality of rear panel openings, the opening edge of each of the protective covers being joined to a corresponding one of the rear panel openings;
- and
- a plurality of printed circuit boards, each of the printed circuit boards configured with at least one vacuum tube,
- wherein each of the printed circuit boards is mounted to a corresponding one of the rear panel openings of the rear panel, so that the at least one vacuum tube electrically connected to the corresponding one of the printed circuit boards is arranged within the containing space of a corresponding one of the protective covers,
- wherein each of the protective covers, the rear panel and a corresponding one of the printed circuit boards are assembled to form a test module.
