    摘要： Output signals given from a tube amplifier (5) are amplified by a small number of vacuum tubes with maintaining the output property of the output signals. A second circuit (C2) is arranged in parallel to a first circuit (C1) wherein the output signals given from a vacuum tube (VA1) is flowing, and a node of the first circuit (C1) and the second circuit (C2) is connected to an input terminal of an output transformer (TR(1)). Since electric current proportioned to current level flowing in the first circuit (C1) flows into the second circuit (C2), current which amplified the output signals given from the vacuum tube (VA1) flows into the primary side of the output transformer (TR(1)). Consequently, by using the tube amplifier containing the small number of vacuum tubes, it is possible to obtain high output power as if it is obtainable by using a large number of vacuum tubes.

    摘要： It is an object of the invention to provide a light-receiving module, in which characteristic of a semiconductor amplifier unit mounted thereon is inspected on the course of fabrication and an outside photosensor do not come to nothing, and a method for fabricating the same. In the package of the light-receiving module, a semiconductor chip, which comprises an amplifier and a inside photosensor for inspecting it, and an outside photosensor for receiving a light signal are allocated. First, the inside photosensor is irradiated with a light for inspecting amplifier, and the output of the amplifier is investigated. In case that the amplifier is recognized as normal, an Al pattern communicated with the input port of the amplifier is cut, and the output port of the outside photosensor is connected with the input port of the amplifier by a bonding wire. Thus, the light-receiving is completed. In case that the amplifier is recognized as inferior, fabrication process is discontinued, and then, circuit elements necessary for fabrication dose not come to nothing.
