The very late electric DDs were probably recorded with a split signal, one for vertical and the other going to a lateral machine for "Needle-Cut" discs, so the shorter playing duration of the latter determined the length of selection. The longest DD by far that I have is a very early violin solo, Sarasate's "Romanza Andaluza" by Isidore Moskowitz, mx 1255, 80011-R, recorded on 18 Sept. 1912, a first-state matte-black engraved label issue which runs within 1/8" of the label area and lasts over five minutes.

The electrical stop will stop the turntable shortly after the last inner groove, right after the music ends, whereas the regular stop must be set for the longest record in the collection & on shorter records will allow the turntable to keep turning until this point is reached. By the way, has anyone noticed that the later diamond discs tend as a rule to have shorter playing times than earlier issues? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of William Zucca Sent: Thursday, February 14, 2013 12:24 PM To: Antique Phonograph List Subject: Re: [Phono-L] Diamond Disc 250 Mystery Well, I am satisfied that I know what the heck it is and how it operated. Only one question remains in my mind about it..................WHY? The manual autostop works fine. Why install a more complex device that requires electricity to do the same thing? Thanks for all the information. Green Mountain Bill On Thu, Feb 14, 2013 at 7:07 AM, DanKj <[email protected]> wrote: > It was offered in new DD machines, so it can be called 'genuine', yes.
