•Ken Vaughn just sent pictures of the player device atop his Wurlitzer electronic organ and it appears to be virtually identical to the "Magic Organ - Organmatic" player I just saved from the scrap heap. [ See 031006 MMDigest, "Organ Roll Player by Automatic Music Corp." ] I certainly think his valv...

•Can someone put a name on the type of expression device used in the Apollophone, and perhaps suggest where I can start looking for a few rolls, as well a replacement head for the phonograph? Any help is greatly appreciated. Cordially, Tom Binnall

•Since I have parted out my "Wurlit" (a fun device with horns, bells and noise-making devices), I have left: (1) a nice vintage baby buggy (organ cart) which has been tastefully converted to hold a Raffin 31/84 organ case; (2) an empty case that could be used for a hand-organ project that fits on th...

•A Wurlitzer CX held six rolls with its automatic roll changing device. Each roll was spooled onto cardboard tube that was held in place with a metal spool. One end of these holding devices was held in place with a knurled brass nut. I made these spools for sale and still have several left in stock ...

•I don't believe anyone has mentioned the 'friction device' on the roll end; to my knowledge most, if not all, 'players' have this device and in most cases the friction is adjustable and on "rewind" the friction is "off". If the friction is adjusted or is too much it will change the 'Tempo' setting...

•Matthew Schultz asked (16.08.18 MMD) if the tracking device in his Schulz player could be modified into a better-working tracker system. There was a discussion someplace on-line a couple of years ago (I can't find it now) about how to add Amphion-style tracker fingers to the tracker bar. The drop-d...

•I don't have an exact answer as to why a device would be named a Seraphone -- people can name things whatever they want to. But my guess is that whoever named it was thinking of seraphim, a type of angels mentioned in the Bible. Thus, the idea was probably to indicate that the device had an angelic...

•Can some kind soul please provide the patent number for the device used to semi-automatically calibrate (set the gap) the Ampico unit valves in the factory? I remember seeing the patent but did not note the number. I believe it worked on the volumetric flow through the valve rather than the travel ...

•Mark Kinsler reminds us of some "nylon cable tie" devices that talked when you ran your fingernail down them. We had them in the UK too. Back in about 1980 a work colleague appeared with one that had an advertising slogan on it. The product was "Fruity Friends Yoghurt" and the strip said "Hello Fru...

•Dan Wilson's excellent article on external piano player devices in MMD 010212 gave some pricing ideas for 65-note and 65/88-note Aeolian Pianola push-up players. Without detracting from his article, I think he is rather high on the prices that need to be paid for these instruments. A good working 6...

•There is a considerable difference between the giving of mechanical music devices and related material to a recognized museum, whose purpose, one supposes, is to display same and provide access to it, as is certainly the case with the many fine organizations mentioned from time to time in the MMD, ...

•I am contemplating the construction of airflow measurement devices to aid me in my restoration of player pianos. Various articles in the MMD Archives indicate that this has been done by others. In order not to reinvent the wheel, would anyone be willing to share what they have done with me? I have ...

•YouTube would seem to have been made for mechanical music devices, but I guess it's hard to get to the insides of the instruments when you're at the Great Dorset Steam Fair. If it was possible, it would have been fun to watch the mechanisms working away, but I suppose they're not so accessible. The...

•I don't think there are any apps and necessary devices to allow you to use your iPad as a MIDI file player. You can, however, use the iPad to remotely control the [stationary] computer connected to the piano. This is the way I control both my E-Valve connected piano and my LX players too. Each pian...

•I was well aware of the limitations of using such devices for making rolls, but was curious nonetheless. Some of the objections Spencer Chase mentioned are things that some of us might be willing to live with, most notably the lack of speed. A Leabarjan perforator is not the fastest machine in the ...

•We often talk of sealing the wood in our pneumatic devices. To give visual evidence of that need, I am sending a picture taken inside an Estey organ chest. When I first acquired this organ over 20 years ago, I didn't do much restoration, but I did give the blower a thorough cleaning. At that time I...

•I am sure there are dozens of opinions about tracking devices used in different player pianos. If the player is tearing up rolls then something is wrong. My all-time favorite is the method that shifts the tracker bar and, if I ever get the time, then that is the system I will install on my Duo-Art...

•I am getting no suction from the expression devices (both bass and treble) to the stack, therefore no play. If I bypass the expression devices, I do have play. Where shall I look to determine why I have suction to the devices but no suction out of them? Ed Bottegal - - - In an attempt to protect th...
