Transistor is a decorative and electronic serif typeface. One of the historical connection was the Didot, development in French. Transistor typeface was designed from the concept and experimentation with electronic circuits. The main typographic proportion are connected with the modern typeface, like Didot where the letterforms are inspired from the point nib pen design approach but also with electronic type style letterforms.

An exquisite Didot font in 18 series Ambroise is a contemporary interpretation of various typefaces belonging to Didot’s late style, conceived circa 1830, including the original forms of g, y, &; and to a lesser extent, k. These unique glyphs are found in Gras Vibert, cut by Michel Vibert. Vibert was the appointed punchcutter of the Didot family during this period. It is the Heavy, whom sources were surest that Jean François Porchez has been used as the basis for the design of the typeface family. In the second half of the 19th century, it was usual to find fat Didots in several widths in the catalogs of French type foundries. These same typefaces continued to be offered until the demise of the big French foundries in the 1960s. Ambroise attempts to reproduce more of what we see printed on paper in the 19th century; a more accurate representation of Didot punches. So, the unbracketed serifs are not truly square straight-line forms but use tiny transitional curves instead. The result on the page appears softer and less straight, particularly in larger sizes. The illustrious Didot family of type founders and printers Every variation of the typeface carries a name in homage to a member of the illustrious Didot family of type founders and printers. The condensed variant is called Ambroise Firmin. The extra-condensed is called Ambroise François. Ambroise Pro brought back to life: fifteen years in the making!
