※“MJ 1970-1979 Circuit Diagram Collection” is a product with the table of contents, preface, etc. in English to make it easier to use for overseas users.
Please note that the text of the Circuit Diagram is in Japanese as the original.
This year marks the 100th anniversary of the first issue of MJ Radio and Experiments, and we have collected audio amplifier circuit diagrams from the history of radio and experiments and will be selling them as electronic versions.
This software is a digital collection of circuit diagrams extracted from the audio-related building articles published in 120 issues of the magazine "Radio and Experiment (at the time)" over a 10-year period, from the January 1970 issue to the December 1979 issue, excluding special issues.
Have you ever thought, "I'd like to see the amplifier circuit that I wasn't able to build back then," or "I'd like to incorporate a circuit type that is no longer used into my homemade amplifier?"
This software is an electronic collection of circuit diagrams extracted from amplifier building articles published in Radio and Experiment (at the time) over the course of 10 years in the 1970s. Some of the circuits use parts that are hard to obtain now, and some are no longer used due to improvements in the performance of parts, but it provides a glimpse into the insight of amplifier builders who knew pre-war vacuum tubes in real time, and the boldness of young engineers who took on the cutting edge of four-channel stereo and DC amplifiers at the time.
It is a "crystallization of wisdom from the heyday of audio" that will not only evoke nostalgia among old fans who remember that time, but can also serve as a collection of ideas for modern researchers who will be responsible for the audio of the future.
This software compiles about 500 circuit diagrams from building articles extracted from issues between January 1970 and December 1979 into PDF files. You can easily find the circuit you want by searching the titles of the building articles that contain the circuits.
