We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

Lab is simple to use, easy to expand and economical to operate JUST PLUG IT IN Fully transistorized Electrofonic Lab has such low power consumption that it can be plugged into an ordinary, existing classroom circuit. Special wiring is eliminated. Absence of vacuum tube heat makes special air conditioning unnecessary. STAKT SMALL, ADD UNITS LATER The elements of the complete Electrofonic Language Lab are designed as modules that can be combined or expanded as desired. LONG-TERM ECONOMY Transistorized design means a smaller electric bill and eliminates frequent checking and replacement of vacuum tubes. Quality construction throughout will keep maintenance costs at a minimum.
