SOLD: Unusual Small Horn w. Reproducer Attached - $55

[Victrola-nut]

Not sure what this goes to, but I was told by another collector that this was an optional attachment intended to add an external horn to a Columbia internal horn phonograph. The back side of the reproducer looks remarkably similar to a Columbia reproducer and the horn is metallic, but not sure if it's aluminum or something else. Anyway, perhaps you have been searching for this hard to find part and now you've found it! Postal Money Order preferred and $5 for shipping anywhere in the Continental U.S. Thanks!

From a previous thread:

The main purpose behind lid-closing on any phonograph is to enhance sound quality by eliminating two sources of undesired sound.

One of these sources is the tinny scratch of the needle or stylus on the surface of the record. Yes, it's part of the recorded output, but it's generated in a way that gives only a small, higher-frequency (and mostly irritating) part of the range of the recording.

The other is the sound off the face of the reproducer's diaphragm that is not facing the connection to the horn. The back side of the diaphragm is at one end of the (ideally air-tight) sound passage to and through the horn. The front side is connected to the stylus or needle bar, and is at least partially open to its surroundings. Sound waves come off of both faces of the diaphragm...but they are out of phase with each other since one comes from the "push" corresponding to the simultaneous "pull" of the motion of stylus or needle. And out of phase waves tend to want to cancel each other.

The front side sound waves will be mainly higher frequencies, which bounce around pretty well, off of nearby cabinet faces or the surface of the record itself. And when they reach your ears along with the same material from the horn, it makes things not sound so good.

Hence, given the choice, we're better off closing the lid.

P.S. There are, of course, exceptions to this. Many portables and some tabletops use their lids as reflectors that extend the effective horn size, so unless the horn exit is outside of the lid you must of course keep it open. I've also seen little gizmos that mount a small horn onto a disc reproducer to capture and project that front side sound...I've never heard one in action, but probably not a very good idea!

And that is what this thing is, and how it is likely to behave. Also worthy of note in this context is Victor's addition of a felt baffle to cover the front side of the reproducer in their orthophonic portables.

None of this is to take away from the fun of owning this gizmo, though!

This is an Add-A-Tone reproducer from about 1923 or so.
I had one that came with my VV-XVI, the original owner
had purchased it as an accessory. Mine actually played
pretty good and did add a little extra to the volume.
I did however sell it. There was one on ebay a few
years ago that sold for about 400.00.
