•Yesterday Eric Bergstrom asked for ideas for his project of automating his rewind/shut-off device. Rather than use a solenoid I would use a automatic door lock unit. You can find them for less than $10 and they provide uniform power from start to end of the stroke. This one is available for four do...

•I was intrigued by Tom Ahearn's reference to an early Aeolian player demonstration device. I would suspect that other player manufacturers produced models and if there are any setting on someone's shelf, I would like to have a chance to bid on them. Several responses have referred to an attempt to ...

•I thought I had seen just about every kind of roll-playing device there is when up popped the ad for the Tel-Electric piano rolls: http://www.ebay.com/itm/381669221416 I am not, however, purchasing the rolls. Further research turned up a YouTube video of the Tel-Electric in operation: https://www.y...

I recently acquired a Seeburg MO which in a previous "restoration" had several pneumatic devices removed. Is there anyone in this group who has an MO and who would be willing to have some detailed discussions with me about the missing pneumatics so that I can begin to build new ones? The MO that I h...

•I think this forum is the best place to get information on musical devices and would anyone know how best to sell a Mira 18 inch that is in suburn condition? Steven Sisk

•One of the factors which is easily overlooked is that virtually all modern MIDI devices employ some form of data buffering. This means that although the data may arrive sequentially, it is stored for a few milliseconds before being used. Doing this buys time for the playing system, enabling it to r...

•This is an event that anyone interested in mechanical music or steam powered devices ought to make it to once (or more) in their lives! I've posted a few of the pictures I took on my web site at: http://people.ne.mediaone.net/rwiegand/GDSF/GDSF_top.htm The pages are rather large if you are on a slo...

•A lot has been written about the recent idea of installing electronic playing devices to a player (or reproducing) piano. I really don't see what is the problem with installing such a player as long as it doesn't modify the original player and/or its ability to play paper rolls. From what I've read...

•I don't know if this amazing lady built any mechanical music devices, but anyone who admires craftsmanship should look at her creations. She did not invent all of the devices shown; some are classic scientific instruments. Also note the quality of the photography. Tatjana van Vark http://www.tatjav...

•As much as I have read here about the falling prices of mechanical music devices, I feel obligated to relate the prices received here in the Northwest. After seeing a link at the bottom of these pages last month to an eBay listing, I found it was for a live auction in Port- land, Oregon, some 2 1/2...

•[ Paul Johnson wrote in 200125 MMDigest -- ] > I have heard sporadically about devices built to aid in the moving > of player grands ... I can't speak for a foot-pumped player grand; I would imagine you will have to remove the foot pumps along with the "normal" pedals. When I moved my player I took...

•The following URL should magically transport you to an extensive list of equally-magical devices that, if you keep them cool, will increase or decrease any DC voltage to any other DC voltage with very little loss. The generic term is 'dc-dc converter' and from all reports they're both inexpensive a...

1. Re: 2nd crescendo for late Ampico: the Ampico B has only one crescendo device operating from the Treble Crescendo channels. I consider the performance of my B piano inferior to the Ampico A when playing most A rolls. I recommend installation of a second crescendo in the late-production A pianos t...

Here's yet another mail-order catalog, but this company has a lot of Midi devices which aren't in computer catalogs and magazines: Musician's Friend P.O.

I recently acquired a 1920 booklet, "Good Times With Your Gulbransen," and it mentions a device called "The Leabarjan Player-Roll Perforating Machine -- a portable instrument designed for the player-piano owner to use in the home," with which one could supposedly cut his own rolls. There's an illust...

The recent discussion about the Player Piano Concert in St. Louis based upon a device built by Craig Brougher brought back some memories. If I'm not mistaken, the music director for that concert was Newton Wayland using one of Bill Singleton's restorations. I participated with him in 3 other similar...

•Hello, Just thought I would point out something about the use of GFI devices (in Australia we call them "RCD" -- Residual Current Devices) when installed in the switchboard. The leakage current of all devices on the circuit add up. So if one device leaks say 10 mA (our RCD's are usually 30 mA) it w...
