Several weeks ago I went to an auction where a local radio club member was selling off most of his collection. He was moving to an apartment from a rural setting.<P>Anyway, among the numerous finds that I made that day was a 1946 Zenith Chairside. Made the year I was born, so it seemed like a natural. It is in fine condition. All original. So far, all I have done is to clean it up and play it in the evenings.<P>My problem is with the record player. This has a automatic changer dual arm cobra unit in it. One arm for 78's another for the 33.33's. The belt slips a little, but it does indeed work. However, I cannot figure out the how the automatic player works. Under the platter is the number S-14060 If anyone has information on this unit, I would appreciate it.<P> <IMG SRC="http://antiqueradios.com/albums/Zenith/Zenith_12H093_record_player.sized.jpg"> <P>Thanks,<P>Rich<P>------------------<BR>

Good old Cobra Matics. They are so cool looking and the green color is rare! If the belt slips it may not be able to transmit enough torque to engage the record drop/tone arm mechanism. It takes a lot more torque to do that than simply turn the table. The number on it is simply Zenith's part number for that item. If you can replace the belt with a new one, clean and lube the mechanism I would bet it would once again play Benny Goodman!<P>------------------<BR>If it glows in the dark and heats up the house, it's MY kind of radio...

Looks like an S14010, going by the number stamped by the spindle. Couldn't find service information for that number, but a later dual arm Cobra instructions (S14012) said 33's must be played manually, only 78's could be played automatically:<BR> <A HREF="http://www.nostalgiaair.org/PagesByModel/648/M0025648.pdf" TARGET=_blank>http://www.nostalgiaair.org/PagesByModel/648/M0025648.pdf</A> <P>You should have a switch for 10 and 12 inch, and manual operation. Any size and speed record can be played manually, but probably only 78's can be used in the automatic posistion, based on the above.<P>Richard<P>------------------<BR> <A HREF="http://www.dressner.com/radio.htm" TARGET=_blank>www.dressner.com/radio.htm</A>

Thanks for the information. I had been trying to get the automatic record changer to work on the 33.33 rmp mode. Last night, I tried on the 78 rmp mode and it works just fine. The red lever on the right side can make adjustments for the size of the record. <P>As you can see, the layout of the tone arms is different on mine. Mine are opposed. There is a button on the top that controls the automatic changer. When records are loaded, you can push the button and a cam turns near the edge of the record and kicks it off to the side. It is rather clever. I will pull it apart this weekend and verify if there is any mechanical problem with the 33.33 rmp mode, but right now it feels loose, like nothing is connected below to control the arm.<P>The only other problem that I am having is that the motor needs time to develop the omph necessary to turn the platter. After several minutes go by, it will work okay, even operating the automatic changer. <P>The advertisements are real cool, mine looks just like the chairside in the top picture of the last ad. <P>Thanks,<P>Rich<P>------------------<BR>

I'm sure there is nothing there, by design. Otherwise, it would have required separate mechanics to operate the second arm, making it hopelessly complicated.<P>Richard<P>------------------<BR> <A HREF="http://www.dressner.com/radio.htm" TARGET=_blank>www.dressner.com/radio.htm</A>
