What would happen if I put an orthophonic soundbox on my 1916 VV-XI tonearm? Or could I get a tonearm from an orthophonic victrola with appropriate sound box and install it on a VV-XI? Has anyone else ever tried this?
The Orthophonic Victrola was designed as a system, and all parts were designed specifically to work together -- the sound box, tonearm and horn. Actually, the tonearm and horn were considered "one unit," in that there was a constant exponential taper from the opening of the tonearm to the mouth of the horn. In order to work properly, the system was designed to be as air tight as possible.
The opening of the Orthophonic sound box's throat is larger than that of the pre-Orthophonic models, so you'd need an adapter to fit it onto the tonearm.
Many years ago, using a homemade adapter, I tried out an Orthophonic sound box on the tonearm of a VV-80 and was not impressed. (The VV-80 was about the same size as the VV-XI.) While louder than the #2 sound box, it had a tendency to blast. The #4 sound box on the same tonearm sounded much better--but still no match for the Orthophonic tone chamber of even the smallest cabinet model, the Consolette (4-3), which has a small, albeit true exponential style horn.
Installing an Orthophonic tonearm & sound box onto a VV-XI would mandate drilling new holes, and making other modifications in order to get it to fit properly. While the tonearm portion would be correct for electrical records, you'd still be left with the earlier, improperly designed horn which adds resonance, etc. to the sound quality.
You're best bet might be to hunt down one of the smaller Orthophonic models such as the 4-3, 4-7 or 4-20. While no match for the Credenza, in terms of bass output, they provide a room-filling full sound, and are a tremendous improvement over any of the earlier models for playing electrically recorded records.
Another option, believe it or not, is the 2-55 portable, which has an amazing performance for it's size--more like a small electrically amplified phonograph.
