Re: [Phono-L] Diamond Disc 250 Mystery
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. I took two pictures of the features that I have described above and would be glad to send them to anyone who asks and who provides me with an email address.

Re: [Phono-L] Diamond Disc 250 Mystery
It was offered in new DD machines, so it can be called 'genuine', yes. I don't think there's any special indication on the ID tag. About 1.5 volts is needed to operate, and that was originally provided by a tall ignition cell - you could use a couple of D cells in parallel, today. My 250 has a square metal battery bracket in the rear-left corner, behind the horn - I've always used cheap 6volt lantern batteries which haven't hurt anything yet (25+ years and thousands of plays) - Original Message - From: William Zucca rochr...@gmail.com To: Antique Phonograph List phono-l@oldcrank.org Sent: Thursday, February 14, 2013 5:42 AM Subject: Re: [Phono-L] Diamond Disc 250 Mystery OK everyone. Thanks. Questions: Was this a genuine Edison option? and if so... Should this this accessory be designated in some special way on the ID tag? was the power source-what type of battery? Should there be a special place below the motorboard to put the battery? ___ Phono-L mailing list http://phono-l.org
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.

[Phono-L] Turntable Motor Question
I am at my wits end, trying to find someone who can rewind/fix a motor for my Fairy Phonograph Lamp. What I am considering as a temporary fix (not altering the original parts in any way) was to use a 78 rpm turntable motor from a jukebox. Does anyone know of a direct drive type motor that would handle the weight of a 12 steel turntable and the resulting drag from the acoustic reproducer and steel needle? I have been researching the original Fairy motor for over 8 months and cannot find anything about it regarding amps, hp and rpms - there is no tag on any of the three that I have looked at. I am restoring a second Fairy lamp that has the same motor problem as my first one - motor spins, but slows to a stop with any load. I have been told that the motor is a strange one since it is wound for three different types of power. Parts for these phonos are non-existent, thus the idea of using a strong jukebox turntable motor which is already running at 78 rpms. The original motor has a resistor to cut the power and uses a pulley - governor - worm screw to meshed gear transmission to run the turntable and the speed is controlled by a simple brake mechanism. Any ideas or suggestions would be greatly appreciated. Curt ___ Phono-L mailing list http://phono-l.org
Re: [Phono-L] Turntable Motor Question
There were a number of direct drive phono motors made back in the 78rpm days. The General Industries Flyer models are among the most common. Other ones that I can think of were used in Webster-Chicago players and changers. These motors date from the 1930s, up to WWII. They are 90 degree worm gear drives direct to the platter spindle. They are robust and would easily drive a platter under the drag of an acoustic reproducer. Most of them were originally used with the old horseshoe magnetic pickups that tracked at the same force as acoustic reproducers. Another option would be to use an induction disc motor from the late 1920s such as used by Victor and Edison (motor made by GE). These are also direct drive and pretty readily available from phono boneyard parts dealers.

Re: [Phono-L] Turntable Motor Question
Thanks for the info Greg. I have looked into Victor and Edison motors, but am somewhat limited by size constraints. The largest size width and length is approx. 6-6 1/2 and maybe 4 deep. I will try to find the others that you mentioned and see what size they are.Thanks again,Curt From: gbogan...@charter.net To: phono-l@oldcrank.org Date: Thu, 14 Feb 2013 23:58:35 -0500 Subject: Re: [Phono-L] Turntable Motor Question There were a number of direct drive phono motors made back in the 78rpm days.
