•The battery is a No. 3710 - 3V - 2R10. The ones I have are 'Varta', distributed in Great Britain by Varta Ltd, Cropmead Industrial Estate, Crewkerne, Somerset TA 18 7HQ, and in France by Varta S.A., 92403 Courbevoie. I try to pick up one or two batteries any time I am in Europe, but I would expect ...

For all those interested, especially in response to Matthew Caulfield, yes, I and my MIDI-controlled hybrid Fairground Organ will be at the North Tonawanda Band Organ Rally next week. I will be anxious to meet all of you who attend. I will be leaving Saturday, first to visit family in NJ, NY, and Co...

Andy, the energy in your storage battery is stored primarily in the compounds on the surfaces of the lead plates, and "topping off" the electrolyte with distilled water won't seriously "dilute the charge"! I suggest that you _use_ the battery when you play L'Orgue Mecanique for your relatives, and t...

•-- non-subscriber, please reply to sender and MMD -- I recently came across the Punch-a-Tune toy "barrel organ" I had as a boy in the 1970s, but no battery. What type of battery does this require? I saw postings on your web site about this. Jacob Hugart [ Bob Billings wrote that the movement is "th...

•Hello Jacob, I have a similar box, "Music In Motion", with Christmas songs from "Mr. Christmas". It had a 120-volt AC to 3-volt DC adapter. Here we have 220 VAC electric power. I use an adapter with an output of 3 volts DC or 4.5 volts DC. If I choose the 3-volt DC output it is a little bit too slo...

•Okay -- the holidays are over, you have played the great little miniature Wurlitzer band organ for everyone you know and probably some you didn't know. I even got a working scale-model carousel to put next to it for a neat Christmas mantel display, and next year will equip it with miniature lights...

•Though Alan Pell is the maker, the electronic assembly is by Melvyn Wright (http://melwright.com/). He is the expert on such matters. I've had my busker organ for 15 years and have replaced the battery countless times, learning that not all are equal. The best source is Batteries Plus. I'm on the r...

•My Pell busker organ is happily playing again, thanks to trouble shooting from Alan Pell and suggestions from several other people. It's problem turned out to be a blown fuse in a not greatly accessible place, but all is now well. Alan pointed out that in his organ the power cord connects to the ba...

•It is great that Tom McAuley was able to find his copy of the Pell Harmonette Instruction Manual, and scan it as a PDF document [250417 MMD]. I also want to thank our hosts for putting in on MMD "for perpetuity." I have seen quite a number of these instruments, but never had charge of one. I have s...

•The electronics in the later Pell Harmonette organs that have a PIN code were made by Melvin Wright. There is also a stutter introduced by the electronics into the playback circuit to make copying the tunes difficult. To this point, I made up some replacement decks that require removing a few screw...

•Hello -- I recently acquired a 1920s-era battery radio that is now at home on display near my Apollo player piano and rolls. The tubes in this radio are prominently visible, so I think it would be interesting to have some QRS "Red Top" radio vacuum tubes to display in the radio. In my opinion, it w...

•I assume that this thing is battery-powered, old, and German. This would mean that it has a small, old, battery-powered motor inside to run the little pumps. If you're lucky, the motor's pivots require only lubrication. In any small DC motor the shaft should turn freely, and can generally be checke...

•Tom Sendall spoke of operating an electric motor with a truck battery and an 800 watt inverter. Although there is plenty of power available with this setup, most cheaper inverters put out what is called a "modified sine wave", a waveform that induction motors do _not_ like at all. In order for the ...

•[ Philip Jamison wrote in 140701 MMDigest -- > Can the lead-acid battery be replaced or improved > with a more modern battery unit? Phil, Hofbauer 'Tanzbaers' have been around for many years so will need their batteries replaced. I would be surprised if their original batteries were lead acid as Ni...

•I need a MIDI that will drive 32 notes and work from a 12-volt battery. If anyone knows of a small unit please let me know. Galen Bird ogmbird@aol.com

•I got my 2016 AMICA convention favor today and played it until the battery went dead; it is on recharge now! Kudos to all who had something to do with this most enjoyable piece -- without a doubt, the best bargain out there for mechanical music fans. All best from Soggy South Texas, Ed Gaida San An...
