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.
FEBRUARY keeps them from sticking to the glass should it ever be removed. Place one gasket in the cup of the reproducer and lay on top of this the glass you wish to insert, taking care to have it exactly in the center and clear of the sides of the cup. , . Place the remaining gasket on top of the glass and clamp in position by means of the tube plate and ring. Lay the reproducer tube plate down, and raise the limit- ing weight off the glass and with a match or toothpick deposit a very small drop of stratena cement directly in the center of the glass. ( Care must be taken not to get too much stratena on the glass as this makes a soft joint and sometimes greatly impairs the tone). Lower the weight and adjust the crosshead to the center of the glass. - This may be done with a pin, needle or any instrument small enough to work through the center hole in limiting weight. The crosshead must be exactly in the center of the glass and in direct line with the end of reproducer stylus arm and it must be set so as not to twist the link but pull straight. If after the cement has hardened (which gen- erally takes from 15 to 30 minutes) you find the cross head is twisted remove the clamp ring and tube plate and turn the glass until crosshead is straight. Always test the reproducer by trying it on a loud band record, and if the result is not satisfactory you must remove the glass and try another. The March Phonogram will contain another chapter on the adjustment of the reproducer, as a great deal re- mains which can be said but for which we have no room ® this number. ( To be continued. )
