[Phono-L] 1930 suitcase RCA Victor

Hi Steve,

The VV 2-65 is by no means rare or even scarce. The one shown in the link
appears to have all of its accessories and the condition is (based on my
acquisitions) better than average (maybe 7 out of 10 where most probably
come in at 6 out of 10 or worse).

I do not know of a source of manufacturing counts for the RCA-Victor
Orthophonic portables but compared to the VV 2-55 I see about 6 or 7 times
more 2-55s than 2-60/65. Maybe Bob Baumbach or Paul Edie has more data - I
have not checked with them. I get a total of about 30 or so Orthophonic
portables per year through my shop, so I don't know how well my estimates
equate with actual production levels and I suspect that because the 2-65s
were made of wood that many would have been trashed long ago compared to the
explosion and bullet proof armored case of the 2-55.

In my hands-on experience, the VV 2-55, because it is a solid metal case,
tends to hold up much better than any of the wooden and fiberboard
concoctions used in the later RCA-Victor machines (or the earlier machines
like the VV-35, 1-X, etc. for that matter). The bonded leather cloth is
problematic on all of them. The 2-65 motor boards are the equivalent of a
Masonite like product (which I call really strong cardboard) and it is
somewhat flimsy. I often put a 2-55 alongside of the 2-65 for comparison
sake and the 2-55 is always the winner. Simple physics dictates that it has
to be so. The 2-65 isn't a slacker really, but the 2-55 just has a bit more
integrity, mass, and horn length (perhaps shape as well). I must say that
the motors and hardware of the latest 2-65s and the 2-60/65s are usually
quite reliable and easily comparable in quality.

Many later Orthophonic reproducers, especially those that bear the
RCA-Victor name have had the spider removed or have no spider at all as you
mention. The needle arm is still soldered to mounting point, but obviously
not on a spider. Are yours RCA-Victor branded parts?

Another curious characteristic to look for in the later RCA-Victor
Orthophonic reproducers is the presence of a diaphragm that resembles that
of the HMV 5A. This is the type that looks almost identical to the Victor
Orthophonic but it has 6 small equally spaced indentations impressed in one
of the ridges (valley as viewed from the front). I have pictures and other
technical writing that I will email to you privately if you want it. They
are standard issue for the HMV 5A (the HMV 5B is a different story and a
step backward IMHO). I have seen the HMV 5A style diaphragm used in late
RCA-Victor Orthophonic 5A reproducers with and without a spider.

I've never really contemplated what might be a good engineering reason for
the variations although the performance of them all, except the HMV 5B, is
quite similar. I do not necessarily agree with those that hold to the
thought that RCA-Victor was just using up whatever was lying around. Those
diaphragms that have NO spider at all (i.e. no left over "toes") may indeed
at least look like a cost cutting measure somehow, but those diaphragms that
still have the "toes" tend to make me think something more technical is in
view. The reason I say that is because clipping the spider free of its
"toes" shows: (1) that the diaphragms were obviously already fitted with
spiders and ready to be used in the way we most often see, (2) labor was
required to remove them and, (3) even more labor was required to install an
alternate mounting point for the needle arm solder connection, and these
things would seem to suggest [to me] something of a technical reason; else,
why bother with all the labor? I'd love to hear what others know on the
subject because most of my writing here is based on pure observation during
restorations.

The pot metal formula used for the Victor and RCA-Victor Orthophonic No.5A
(i.e. portable style) is indeed a much more stable alloy. In fact, I have
only seen one 5A with pot metal problems. Although I do not have the
capability to analyze the composition of the various pot metal alloys, I
tend to think that the percentage of zinc that was used in the early alloys
was too high (probably because the zinc was the cheapest metal in the
alloy?). If anyone else has specific knowledge of metallurgy and any test
data that shows the percentages of metals used in the different alloys I
would love to see it.

Walt

How rare are these and is it a VV2-65?
