Hi Mario, Some reproducers are harder to find like the gold and antique finish Dance and the square weight Edisonic and this is the first square weight NOS Edisonic I have seen. This is serial number F-75662-NS which means that Edison converted it over from a regular reproducer to an Edisonic. For $6.75 plus your old reproducer Edison would give you an Edisonic, saving you $12.75 off of the $19.50 cost of the Edisonic. Edison then took the old reproducer and installed a larger limit loop, the thicker diaphragm and the new heavy weight. Since this one has a high serial number I would guess that Edison converted it from unsold stock. The early square weight Edisonic is harder to find than the Dance in my experience. One of the antique finish Edisonic reproducers I have is F 80885 NS while my antique finish square weight is F 79001 NS. I do not know if all the square weights were converted ones, but they are hard to find. I read that when Edison went out of business in 1929 a San Francisco dealer threw his entire stock into the bay, except for some Edisonic reproducers that were rescued and NOS and sold for years. Rare items such as NOS keep going up in value and who else knows of an NOS square weight nickel Edisonic? Edison reproducers have letters before the serial numbers: LG is long playEM is one with Duncan stopLD is the Danceno letters & A to F Regular DD reproducerEdison started out with just numbers and when he got so high (999999) he started over with an A and worked his way up. NS before the serial number EdisonicNS after the serial number Converted EdisonicYou could trade in a regular reproducer and $6.75 and save $12.75 on anEdisonic, Edison then modified the head with a larger limit loop and installed the heavy weight and thicker diaphragm on it. > From: marioaf at optusnet.com.au> To: phono-l at oldcrank.org> Date: Thu, 30 Nov 2006 08:20:36 +1100> Subject: [Phono-L] Am I missing something here> > Hi Listers,> > Am i missing something with edisonic Reproducer???> > http://cgi.ebay.com/NOS-Edison-Diamond-Disc-EDISONIC-reproducer-w-box_W0QQitemZ220052821260QQihZ012QQcategoryZ38029QQrdZ1QQcmdZViewItem> > Cheers,> Mario> _______________________________________________> Phono-L mailing list> Phono-L at oldcrank.org> > Phono-L Archive> http://phono-l.oldcrank.org/archive/> > Support Phono-L> http://www.cafepress.com/oldcrank
