Re: [Phono-L] Diamond Disc 250 Mystery
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: phono-l-boun...@oldcrank.org [mailto:phono-l-boun...@oldcrank.org] 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.

Re: [Phono-L] Diamond Disc 250 Mystery
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.

Re: [Phono-L] Diamond Disc 250 Mystery
I believe that's because they were waxing both Needle-Type and Diamond Discs at the same time, so could only fit what would go on the shorter Lateral sides. - Original Message - From: Jim Cartwright jim...@earthlink.net .

hi bill i have one on one of my machines its an electric cut off on the dd zono -Original Message- From: William Zucca rochr...@gmail.com To: Antique Phonograph List phono-l@oldcrank.org Sent: Wed, Feb 13, 2013 9:19 pm Subject: [Phono-L] Diamond Disc 250 Mystery Hello Phonolisters: Today while I was out looking for records I came across an Edison Diamond Disc player, model 250 that had several items that I have never seen before. Attached to the bottom of the brass portion of the top of the horn just behind the locking ferrule is a small brass pipe that runs down below the motorboard and contains an electrical wire that starts with a small phonetip on the upper end and ends in a bare end below the motorboard. The wire is about 18 long. Also interesting is an electric switch below the turntable that seems to be part of the stop mechanism. Other than that, the machine seems to be an ordinary 250 with a spring motor.

It's the Duncan Automatic Stop ! That phonetip plugs into a little hole on the back of the reproducer; when the limit pin touches the loop, the Duncan stops the phono for you. - Original Message - From: William Zucca rochr...@gmail.com To: Antique Phonograph List phono-l@oldcrank.org Sent: Wednesday, February 13, 2013 9:05 PM Subject: [Phono-L] Diamond Disc 250 Mystery Hello Phonolisters: Today while I was out looking for records I came across an Edison Diamond Disc player, model 250 that had several items that I have never seen before.
