Hello everyone. Today I breyed to my old tape recorder and decided to assemble my own. I know, it sounds crazy, but in general I don't see anything complicated in analog circuits (except for the tape broaching mechanism). So that's my idea. Make/or find drawings of the head block for 48-56 channels (erasing, recording and reading), order the heads at the factory, build a mechanism, control unit, and add preamps and correctors (to set up the tape recorder, you don't know phono correctors). Sony APR24, Studer A80, Studer A827 became the basis or ideal I strive for. I would like to be helped here in the implementation of the experience in the creation of such mechanisms. I would share in the discussion my experience in creating this particular model. I will also be grateful if you share the schemes from such projects. My idea is very interesting, but incredibly complicated. I will be glad if I can implement it with your help.
