The Talking Machine Forum — For All Antique Phonographs & Recordings

Does anyone own it ? It is such an interesting machine and I am curious to know how does this sound? Any videos will be appreciated.
Thanks

If you post this under ‘Machines’ you will find quite a few US collectors who do or have owned one. There will be much more experience of them there than in Europe.

I believe the expectation is that they would produce more volume but hardly do.

All the same, fascinating machines.

Thanks for the suggestion. I just noted a brand new twin horn gramophone presented for sale on eBay https://www.ebay.com/itm/265355980789?m ... media=COPY

Of course originating from India and with a HMV decal .

*Obviously a fake one

Here’s a video of one that I sold a few months ago: https://youtu.be/wgl74yImRkQ

I have another one available page 6 of my website, but haven’t had the time to make a video yet: https://www.musicaltreasuresofmiami.com/6-phonos

Thank you for sharing! Very impressive collection put up for auction. I never knew about Duplex.

After this posting I tried to compare videos of the Kalamazoo Duplex. This doesn’t really tell me much as you have to be there in person. However I did discover one fascinating thing:

Good Heavens! You know I actually counted no less than 9 coin-operated phonographs in that video. I watched it several times and it’s true...

and I’d like a copy of that record.

I'd think the sound from one horn would be 180 degrees out of phase with that from the other, meaning the two would tend to cancel each other out.

Exactly right !! Out of phase.

What I find interesting about this machine is the winding handle suggests it has a repurposed motor possibly form a HMV 102. The tonearm looks like it is from a portable too.
Whilst these fake machines are often referred to as reusing vintage parts, many of the machines currently being made seem to have all new parts, with copies of Garrard or Thorens motors
